Applications
The TPS4H000BQPWPRQ1 is designed for automotive body control modules managing resistive and inductive loads such as relays, solenoids, LED lighting strings, and fan motors on a 12 V or 24 V vehicle bus. Its integrated protection and SPI diagnostics enable intelligent load management with real-time fault detection in ADAS power distribution units and door control electronics. Fleet vehicle telematics units and truck body controllers operating at 24 V also use this device to safely switch multiple external loads while satisfying ISO 16750 automotive electrical robustness requirements.

Frequently Asked Questions
How many load channels does TPS4H000BQPWPRQ1 switch, and what voltage can each channel handle?
The TPS4H000BQPWPRQ1 provides 4 independent high-side switch channels, each rated for a maximum supply voltage of 40 V and a maximum continuous current of approximately 1 A per channel based on the 1000 mΩ on-resistance and thermal limitations. This configuration enables switching of up to 4 separate 12 V or 24 V automotive loads—such as solenoids, relays, or LED lighting—from a single IC, simplifying body control module designs.
What protections does TPS4H000BQPWPRQ1 provide for inductive automotive loads?
The device integrates over-current limiting, over-temperature shutdown with auto-restart, under-voltage lockout, and active clamp protection against inductive voltage spikes up to 40 V transients. When driving relay coils or solenoids that generate large back-EMF during turn-off, the active clamp absorbs the inductive energy within the IC without requiring external freewheeling diodes, reducing BOM complexity and protecting the automotive ECU from voltage spikes on the 12 V bus.
How does the SPI interface on TPS4H000BQPWPRQ1 support automotive system diagnostics?
The SPI interface allows the host MCU to read per-channel fault status registers reporting over-current, over-temperature, open-load, and short-to-ground conditions for each of the 4 switch channels. Diagnostic read cycles complete in under 1 µs at standard SPI clock rates of 1 MHz, enabling the body control module to detect and log load faults in real time without additional external sensing resistors or comparators, simplifying ISO 26262 functional safety implementations.
Is TPS4H000BQPWPRQ1 suitable for 24 V truck body controller applications?
Yes, the TPS4H000BQPWPRQ1 supports a supply voltage up to 40 V, which comfortably accommodates 24 V nominal truck electrical systems including ISO 16750-2 load dump transients up to 35 V. The AEC-Q100 qualification and -40°C to +125°C operating temperature range ensure reliable operation in commercial vehicle environments subject to vibration, humidity, and extreme temperature cycles encountered in heavy truck and trailer applications.
How does TPS4H000BQPWPRQ1 compare to a discrete MOSFET plus gate driver solution for a 4-channel automotive switch?
A discrete solution requires 4 MOSFETs, 4 gate drivers, 4 current sense resistors, and external protection circuitry, typically occupying over 400 mm² of PCB area. The TPS4H000BQPWPRQ1 integrates all 4 switches, gate drive, protection, and SPI diagnostics into a single 20-pin SOIC package measuring approximately 7.5 mm x 5 mm, reducing component count by more than 15 parts and PCB area by over 60%, while adding features such as open-load detection that are difficult to implement discretely.
