BTS5014SDAAUMA1 Overview
Key specifications include an operating supply range up to 28V nominal (with load-dump tolerance to 41V typical), very low standby current, and proportional load current sensing via the IS pin. The device integrates a charge pump that drives the gate of the N-channel MOSFET above the battery rail, enabling true high-side switching without the cost of a P-channel device, and provides diagnostics such as fault feedback and open-drain status output.
A high-side switch (HSS) is a power distribution IC that connects a load (lamp, solenoid, motor, heater) to the positive battery rail under microcontroller control while providing on-chip protection. Compared with discrete MOSFET plus fuse approaches, integrated smart switches reduce PCB area, eliminate the external fuse, and provide programmable current limits plus fault telemetry to the ECU. They sit within the broader power management IC hierarchy as load drivers, distinct from voltage regulators that maintain a constant rail.
The BTS5014SDA family is fabricated in Infineon's automotive-qualified SMART7 process technology, which combines the power MOSFET, charge pump, control logic, and ESD protection on a single die. This monolithic integration ensures consistent RDS(on) and protection behavior across the full automotive temperature range of -40C to +150C junction, and supports PPAP documentation for OEM tier-1 use.
Typical applications include automotive body electronics (lighting, door locks, seat heaters), industrial 24V PLC output modules, and any 12V/24V load that requires resettable over-current protection rather than a one-shot fuse. The current sense output enables closed-loop load monitoring for bulb-out detection or wire-break diagnostics. A recommended design tip is to place a reverse-polarity protection device (Schottky diode or P-FET) on the supply line, since the BTS5014SDA does not include reverse-battery blocking internally.

Typical Applications
BTS5014SDAAUMA1 is suitable for 6 applications: Automotive Body Lighting (HID/LED Headlamp, Tail Lamp), Industrial 24V PLC Digital Output Module, Solenoid and Valve Driver, DC Motor Driver (Brushed, Low-Power), Resistive Heating Element Driver (Seat Heater, Mirror Heater), Battery-Powered Power Distribution / eFuse Replacement.
Automotive Body Lighting (HID/LED Headlamp, Tail Lamp)
The BTS5014SDAAUMA1 drives 12V automotive lamp loads up to 6A directly from the battery rail. Its integrated current-sense output enables bulb-out detection by comparing nominal vs. failed-lamp current, while over-temperature and over-current protection replace the legacy fuse. Used between VBB and the lamp with a flyback diode for inductive wiring. Compared with discrete MOSFET + fuse, this part reduces PCB area by ~40% and adds resettable protection plus diagnostic telemetry to the BCM.
Recommended
Industrial 24V PLC Digital Output Module
In a 24V industrial PLC output, the BTS5014SDAAUMA1 switches the load with logic-level input from the PLC CPU and reports fault status back via the ST pin. Its 28V nominal supply rating covers the industrial 24V rail with margin, and the current-sense output supports wire-break detection in field installations. The -40C to +150C junction range meets IEC 61131-2 environmental specs for factory-floor PLCs, while integrated short-circuit protection eliminates the need for external fusing per channel.
Recommended
Solenoid and Valve Driver
Driving 12V/24V hydraulic or pneumatic solenoids from the BTS5014SDAAUMA1 provides controlled inrush handling and inductive flyback protection built into the IC. The current limit protects against stuck-valve conditions, while the ST pin flags short-to-ground or open-load faults to the controller. Unlike discrete solutions, no external freewheeling diode is required for typical solenoid turn-off energy, simplifying the BOM and improving MTBF in industrial valve manifolds.
Recommended
DC Motor Driver (Brushed, Low-Power)
For small brushed DC motors in HVAC flaps, mirror adjusters, or seat-position actuators, the BTS5014SDAAUMA1 provides high-side switching with current limiting to detect stall conditions. The IS pin output can be fed to an ADC to measure motor current in real time, enabling soft-start and stall detection algorithms. Pair with a complementary low-side switch from the same Infineon family for full H-bridge control of bidirectional DC motors up to ~60W.
Recommended
Resistive Heating Element Driver (Seat Heater, Mirror Heater)
The BTS5014SDAAUMA1 drives resistive PTC heating elements with up to 6A continuous current, replacing electromechanical relays with silent, solid-state switching. The integrated current sense supports closed-loop temperature control when combined with an NTC sensor, and over-temperature shutdown prevents fire hazards in fault conditions. Compared with automotive relays, this approach eliminates audible click, extends lifetime beyond 1M cycles, and enables PWM-based power modulation for proportional heating.
Recommended
Battery-Powered Power Distribution / eFuse Replacement
In 12V distributed power architectures (telecom, e-bike, robotics), the BTS5014SDAAUMA1 replaces blade fuses with a resettable electronic fuse that reports fault status to the system controller. Its 28V nominal and load-dump tolerance cover lead-acid battery transients, while sub-milliohm RDS(on) minimizes conduction loss. The ST pin output can wake the MCU on fault, enabling predictive maintenance - impossible with traditional one-shot fuses.

Key Differentiators
- Highest 6A current in SMART7 PG-TO252-5-11 family (vs BTS5012SDAAUMA1)
- Lower cost than PROFET alternatives (vs BTS6142DAUMA1)
- Automotive-grade SMART7 process vs industrial-only ITS family (vs ITS41K0SMENHUMA1)
Design Notes
At 6A continuous load in PG-TO252-5-11, the tab should be soldered to a copper pour of at least 1 square inch on top and bottom layers to keep junction temperature below 150C. Estimated: with theta_JA of ~40 C/W on a 1 sq-in 2-layer FR4 board, full-load dissipation of 0.5W (RDS(on) ~14 mOhm) yields ~20C rise above ambient - acceptable. For PWM loads near 100% duty or sustained currents above 4A in enclosed spaces, add a small clip-on heatsink or increase copper area to 3+ sq-in.
The BTS5014SDAAUMA1 does NOT include reverse-battery protection. A reverse-polarity event will forward-bias the body diode of the internal MOSFET and may destroy the IC. Always add a series Schottky diode (e.g., 30BQ100) or P-FET reverse-polarity block on VBB. Additionally, the IN pin is CMOS-compatible but should not be left floating - tie to GND with 10kOhm if driven by open-drain MCU. Source: Infineon application note on PROFET reverse-battery handling.
Place the VBB decoupling capacitor (100nF ceramic + 10uF electrolytic) within 5mm of the VBB pin to handle load-dump transients and PWM edge currents. The IS pin output impedance is high - route the IS trace away from switching nodes and add a small RC filter (1kOhm + 100nF) if noise-sensitive ADC sampling is required. The tab land pattern should match the standard DPAK-5 footprint (3.8mm x 6.5mm with 1.5mm tab).
