What is TPS1HC100B-Q1 used for?
The TPS1HC100B-Q1 is used in automotive body control modules, HVAC blower motor switches, and exterior lighting drivers where a single 2.5 A smart high-side switch with fault reporting replaces a discrete MOSFET and protection circuitry. Its 100 mΩ on-resistance and AEC-Q100 qualification make it well suited for 12 V rail loads that require reliable current control and diagnostics over an automotive lifetime. The device is also applied in industrial equipment and building automation where a compact, protected load switch reduces board complexity and improves system robustness.

Frequently Asked Questions
How does the 100 mΩ on-resistance of the TPS1HC100B-Q1 affect power dissipation at its 2.5 A rated current?
At 2.5 A through 100 mΩ, the conduction loss is 0.625 W (P = I²R), which is well within the thermal rating of the small-outline package and keeps junction temperature rise moderate under normal 12 V automotive operating conditions. This low loss reduces heat sink requirements and improves overall system efficiency compared to higher-resistance discrete high-side switches.
Which fault conditions does the TPS1HC100B-Q1 detect, and how does it communicate them to the host ECU?
The TPS1HC100B-Q1 detects overcurrent faults above the 2.5 A threshold, overtemperature conditions, and open-load failures on the output rail. These faults are flagged through a dedicated diagnostic output pin that the host ECU can sample via GPIO, enabling rapid fault isolation in 12 V body control modules without separate current sense amplifiers.
For an automotive designer replacing a discrete MOSFET with the TPS1HC100B-Q1, what integration benefits justify the switch?
The TPS1HC100B-Q1 integrates a gate driver, 100 mΩ MOSFET, overcurrent protection, thermal shutdown, and open-load detection in a single small-outline package, eliminating at least four discrete components. AEC-Q100 qualification confirms the device meets automotive quality and reliability standards across a -40°C to +125°C temperature range, reducing design risk and simplifying PPAP documentation.
