BTS710336ESPXUMA1 Overview
What is a SPOC high-side switch? SPOC (Smart Power Switch) devices integrate one or more N-channel MOSFETs with diagnostic, protection, and gate-drive circuitry into a single IC, replacing discrete MOSFETs plus fuse, sense resistor, and protection circuitry. SPOC devices sit within the broader power management IC hierarchy as smart, protected high-side or low-side switches, typically used in automotive body electronics (BCM), industrial PLCs, and any system needing reliable, diagnosable load driving with built-in protection. They sit below a system-level power management IC in the abstraction stack but above discrete power MOSFETs.
Key features include very low standby current, integrated reverse-battery protection with self-diagnosis, capacitive load switching capability, ground-loss robustness, and a serial peripheral interface (SPI) for configuration, channel control, and diagnostic feedback. The device operates from a wide supply range typical of 12V/24V automotive buses, and offers PWM capability for each output. On-chip protection features include over-load, over-voltage, over-temperature, and short-circuit shutdown, plus a defined restart strategy after fault clearing.
Architecturally, the BTS710336ESPXUMA1 combines five independent high-side driver channels with a common SPI control block, gate drivers, charge pump, current-sense analog front end, and protection logic. The exposed pad of the PG-TSDSO-24-42 package provides a low-thermal-resistance path (PG-TSDSO denotes a power-grade TSDSO with thermal slug), essential when dissipating the power of four parallel switches on a small PCB area.
Typical applications include automotive body control modules driving lighting, HVAC blowers, and seat heaters, as well as industrial PLC output modules and 24V factory-automation actuators. Its small PCB footprint makes it suitable for space-constrained, high-channel-count load driver boards.
When designing with this part, ensure the exposed pad receives sufficient copper area for heatsinking and that the SPI lines are correctly pulled to the MCU's logic domain. SPI command sequencing must follow the datasheet exactly to avoid latch-up after fault events, and unused channels should be left open or tied to ground per datasheet guidance.

Typical Applications
BTS710336ESPXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), Automotive LED Lighting Drivers, HVAC Blower and Fan Control, Industrial 24 V PLC Output Modules, Seat Heater and Comfort Module, 24V Factory Automation Actuator Drivers.
Automotive Body Control Module (BCM)
The BTS710336ESPXUMA1 is purpose-built for automotive body control modules, where it drives resistive and inductive 12 V loads such as interior lighting, exterior lamps, HVAC blowers, and seat heaters. Its five-channel architecture (1.5 A/1.5 A/1.5 A/3 A/3 A) maps directly to typical BCM channel assignments - three low-current lighting/signaling channels and two higher-current motor/heater channels. The integrated SPI interface returns per-channel fault and current-sense data, enabling the BCM microcontroller to implement ISO 26262 diagnostic coverage without external sense resistors. AEC-Q100 qualification and reverse-battery protection meet automotive 12 V/24 V bus requirements, while the PG-TSDSO-24-42 exposed-pad package keeps PCB area minimal.
Recommended
Automotive LED Lighting Drivers
The BTS710336ESPXUMA1's three 1.5 A channels are ideal for driving automotive LED front-lighting, tail-lighting, and daytime-running-lamp modules. The device's PWM capability per channel enables precise brightness control for DRL and turn-indicator fade effects, while integrated over-temperature and short-circuit protection prevents catastrophic failure if a wiring fault or LED short occurs. SPI diagnostics report open-load, short-to-battery, and short-to-ground conditions for ASIL-compliant fault handling. Compared to discrete MOSFET drivers, the BTS710336ESPXUMA1 replaces five MOSFETs, five fuses, and five sense resistors with a single IC, reducing PCB area and BOM cost in space-constrained lighting ECUs.
Recommended
HVAC Blower and Fan Control
The two 3 A channels of the BTS710336ESPXUMA1 comfortably drive HVAC blower motors, radiator fans, and similar inductive loads up to 36 W at 12 V. The high-side switch topology eliminates ground-loop concerns and supports PWM speed control across the full duty-cycle range. Built-in over-current and over-temperature shutdown protect the IC during motor stall conditions, while reverse-battery protection shields the device against jump-start mis-wiring. The PG-TSDSO-24-42 exposed pad provides the thermal headroom needed for sustained 3 A loads, especially in under-hood environments where ambient temperatures exceed 85 C.
Recommended
Industrial 24 V PLC Output Modules
The BTS710336ESPXUMA1's diagnostic-rich SPI interface and rugged protection suite make it well-suited for industrial 24 V PLC digital output modules. Each channel can drive solenoids, valves, indicator lamps, and small relay coils with full over-current and over-voltage protection. The reverse-battery and ground-loss robustness specified in the SPOC family simplify IEC 61131-2 compliance for industrial control cabinets. SPI feedback enables per-point fault indication at the PLC HMI, reducing field-service troubleshooting time. The PG-TSDSO-24-42 package footprint allows eight modules to fit in a standard 16-point PLC output card.
Recommended
Seat Heater and Comfort Module
Automotive seat-heater modules require multiple PWM-controlled heating elements, each drawing 2-5 A. The BTS710336ESPXUMA1's combination of 1.5 A and 3 A channels can drive seat heaters, backrest heaters, and cushion-ventilation blowers from a single IC. SPI control allows the body controller to implement soft-start ramp profiles, individual-zone temperature monitoring, and fault logging for warranty analytics. Over-temperature protection shuts the heater down if the seat sensor fails, satisfying FMVSS 302 flammability requirements. The compact PG-TSDSO-24-42 footprint fits inside the seat-control module enclosure without thermal-stress concerns.
Recommended
24V Factory Automation Actuator Drivers
In 24 V factory-automation cabinets, the BTS710336ESPXUMA1 drives solenoid valves, small pneumatic cylinders, and indicator stacks with full per-channel diagnostic feedback via SPI. The wide operating voltage range typical of 24 V industrial supplies tolerates 18-32 V bus transients per IEC 61131-2. Each channel's PWM capability enables proportional valve control, while the integrated short-circuit and over-temperature protection eliminates the need for external fuses - reducing cabinet wiring complexity. The PG-TSDSO-24-42 exposed-pad package simplifies thermal management when multiple modules are stacked in DIN-rail enclosures.

Key Differentiators
- Five integrated high-side channels in single PG-TSDSO-24-42 package (vs Discrete N-MOSFET + fuse + sense resistor per channel)
- Integrated reverse-battery protection with self-diagnosis (vs Discrete high-side designs require external reverse-polarity P-MOSFET)
- SPI-based digital diagnostics (per-channel fault, current sense, open-load) (vs VNQ5E160K (STMicroelectronics) parallel-only interface)
Design Notes
Estimated: at VIN=14 V (load-dump-pruned automotive rail) with all five channels active at full rated current, total worst-case dissipation approaches (14-0.5) V * 10.5 A ~= 142 W if all channels were simultaneously at peak. In practice, channels are time-multiplexed or duty-cycled, but the PG-TSDSO-24-42 exposed pad must be soldered to at least 1 square inch of 2 oz copper to keep junction temperature below 150 C. Add thermal vias under the pad to the opposite copper layer for further reduction in theta_JA. Sustained 3 A on both 3 A channels requires significant copper area; verify with the Infineon thermal simulation model.
Place the PG-TSDSO-24-42 exposed pad with a continuous copper plane on the top layer, stitched with thermal vias (typically 0.3 mm drill, 1 mm pitch, 9-12 vias) to a bottom-layer heatsink plane. Keep high-current OUT traces wide (>= 50 mil per ampere) and minimize loop area between VBB and the load to reduce inductive transients on switch-off. Place the SPI bus traces (CSN, CLK, SDI, SDO) away from the OUT traces and consider ground-guard traces to prevent coupling. Add a 100 nF ceramic decoupling capacitor as close as possible to the VBB pin and a 10 uF bulk capacitor nearby to suppress load-dump transients.
Do not apply reverse-battery voltage directly without ensuring the load circuit includes a free-wheeling diode for inductive loads - the integrated reverse-battery protection protects the IC but does not absorb inductive kickback. Always read the SPI status register after any fault event before re-enabling the channel; the SPOC device enters a latched-off state that requires explicit SPI command to clear. For unused channels, follow the datasheet recommendation (typically tie to GND or leave open) - never float an unused OUT pin. Ensure VS logic supply rises before VBB to avoid latch-up at power-up; a small RC delay on VS may be required.
The SPI bus operates at the logic level set by VS (typically 5 V or 3.3 V). Keep SPI traces under 50 mm if operating above 5 MHz to avoid ringing; add source-series termination (50-100 ohm) on CLK and SDO lines if reflections appear. The SDO line is high-impedance when CSN is high, so a weak pull-up (10-100 kohm) is recommended to define the idle state. Use a common ground reference between the MCU and BTS710336ESPXUMA1 with a single-point ground connection at the IC's GND pin to avoid ground-bounce-induced SPI errors during high-current switching.
