BTS5210GXUMA1 Overview
A smart high-side power switch is a semiconductor device that connects a load to the positive supply rail while integrating protection, diagnostics, and driving functions into a single IC. In the broader power management hierarchy, it sits between a discrete MOSFET plus fuse and a fully programmable multi-channel PMIC; PROFET+ family parts such as the BTS5210G sit alongside eFuse ICs, low-side switches, and H-bridge drivers, all serving the role of controlled power distribution to actuators, lamps, and relays.
Key features include very low standby current, fast demagnetization of inductive loads, stable behavior at undervoltage, and improved electromagnetic compatibility (EMC) for automotive EMI/ESD environments. The monolithic SIPMOS chip-on-chip technology combines the power stage and control logic on the same silicon, reducing footprint and parasitic inductance. Both channels feature independent diagnostic feedback for short-circuit, open-load, and overtemperature detection, allowing the host microcontroller to flag wiring faults before they damage downstream loads.
Typical applications include automotive body electronics (door modules, mirror heaters, seat controllers), industrial 24 V PLC outputs, relay and solenoid replacement, LED string driving, and resistive/inductive load switching in harsh environments. The device is AEC-Q100 qualified for automotive use, making it suitable for safety-relevant and non-safety-relevant loads that require robust on-board diagnostics.
When designing with the BTS5210GXUMA1, ensure the input pins are tied to valid logic levels (CMOS thresholds) and that the status outputs are pulled up to the logic supply. A small RC filter on the input pins is often used to suppress conducted noise. Thermal dissipation must be calculated using the worst-case on-resistance (140 mΩ) and the expected duty cycle of each channel.

Typical Applications
BTS5210GXUMA1 is suitable for 6 applications: Automotive Body Electronics - Door Modules, Automotive Relay and Solenoid Replacement, 24 V Industrial PLC Digital Outputs, LED Lighting and Signage Drivers, Resistive Load Switching in Harsh Environments, Generic Power Distribution and Hot-Swap.
Automotive Body Electronics - Door Modules
The BTS5210GXUMA1 fits automotive door-module applications where two independent loads such as mirror heaters and puddle lamps need controlled switching from a 12 V battery rail. Its 5.5 V to 40 V supply range tolerates cold-crank dips down to 6 V and load-dump transients up to 40 V, while the 140 mΩ on-resistance keeps channel dissipation under 1 W at 1.5 A steady-state load. Embedded status feedback lets the body control module detect open-load and short-circuit wiring faults before they damage downstream actuators.
Recommended
Automotive Relay and Solenoid Replacement
Replacing electromechanical relays with the BTS5210GXUMA1 reduces PCB area by roughly 50% versus a discrete MOSFET plus flyback diode solution, while adding diagnostics that detect welded-contact-equivalent faults in the load. Each channel handles 1.8 A continuous current and supports fast inductive demagnetization, which is critical when switching solenoids at 24 V. The CMOS-compatible inputs interface directly to 3.3 V or 5 V microcontrollers, eliminating level-shifters between logic and power domains.
Recommended
24 V Industrial PLC Digital Outputs
In industrial PLC and process-control systems running on 24 V rails, the BTS5210GXUMA1 provides two isolated high-side outputs per chip with AEC-Q100 robustness at a fraction of the cost of industrial-grade eFuse ICs. Its 1.8 A per-channel current handles typical PLC loads including relays, contactors, indicator lamps, and 24 V valve coils. The device's 40 V maximum supply rating and embedded thermal shutdown protect against field-wiring mistakes such as miswired 24 V AC or accidental short-to-ground events.
Recommended
LED Lighting and Signage Drivers
For 12 V and 24 V LED strings in automotive interior lighting, architectural signage, and indicator panels, the BTS5210GXUMA1 drives each channel at 1.8 A with PWM-capable inputs for dimming. The CMOS-compatible logic inputs accept 100 Hz to 1 kHz PWM signals directly from microcontrollers, and the 140 mΩ on-resistance keeps switch dissipation low even at the full 1.8 A load. Diagnostic feedback flags open-circuit LED failures that would otherwise be invisible to the system.
Recommended
Resistive Load Switching in Harsh Environments
The BTS5210GXUMA1's AEC-Q100 qualification, -40 °C to +150 °C junction temperature range, and improved EMC behavior make it ideal for switching resistive loads in harsh automotive underhood and chassis environments. Heating elements, PTC heaters, and sensor supply rails benefit from the embedded short-circuit and overtemperature protection, which prevents catastrophic failure when wiring is damaged by vibration. The PG-DSO-14-37 package's exposed thermal pad supports sustained 1.5 A operation with proper PCB copper area.
Recommended
Generic Power Distribution and Hot-Swap
Beyond automotive and industrial verticals, the BTS5210GXUMA1 serves as a generic two-channel hot-swap controller in 12 V and 24 V embedded systems where protected power distribution to daughter cards or peripheral modules is required. Its current limit and thermal shutdown features prevent backplane collapse during fault insertion, and the dual-channel integration halves the BOM cost versus two discrete high-side switches. Status outputs feed back to a microcontroller or LED driver for fault indication in the host system.

Design Notes
Estimated: At 1.5 A continuous per channel with 140 mΩ on-resistance, each channel dissipates approximately 0.32 W; with both channels at full load total dissipation approaches 0.63 W. Using the PG-DSO-14-37 exposed-pad package with theta_JA of approximately 36 °C/W on a 1 square inch copper pour, junction temperature rises roughly 23 °C above ambient. For sustained 1.8 A operation in enclosed automotive environments, expand copper area to 2-3 square inches or add thermal vias to inner ground planes.
Connect the exposed thermal pad (TAB) to a large GND copper pour with multiple thermal vias to inner layers for best thermal performance. Place input, status, and Vbb bypass capacitors within 5 mm of their respective pins; a 100 nF ceramic on Vbb and 10 nF on each status pin suppress conducted EMI. Keep high-current OUT traces wide (≥1 mm per ampere) and minimize loop area between OUT and load GND return to reduce inductive ringing during turn-off.
Do not leave the status pins (ST1, ST2) floating if unused - they are open-drain outputs that require a pull-up resistor to the logic supply (typically 10 kΩ to 3.3 V or 5 V). Failing to pull them up leaves the host microcontroller reading intermittent low levels, causing false fault flags. Also avoid driving IN1/IN2 with signals slower than 1 µs rise time; slow edges can cause partial turn-on and excessive dissipation in the FETs. Always respect the maximum Vbb of 40 V including transient overshoot.
Separate logic ground (GND pin) and power return paths where possible, joining them only at the device GND pin to avoid ground bounce coupling into the CMOS input thresholds. Place the input RC filter (typically 10 kΩ + 1 nF) within 3 mm of IN1 and IN2 pins to reject automotive transient noise per ISO 7637-2. For PWM dimming of LED loads, route the IN pin away from the OUT trace to avoid capacitive coupling that could latch the channel partially on.
