Frequently Asked Questions
What RDS(on) does TPS1HA08AQPWPTQ1 provide and how does it reduce power dissipation in a 12 V automotive load switch at 5 A?
The TPS1HA08AQPWPTQ1 has an 8 mΩ typical RDS(on), so at 5 A the conduction power dissipation is I² × R = 25 × 0.008 = 200 mW. This low figure keeps junction temperature well within limits in a 16-pin SOIC without requiring an external heatsink, enabling compact and high-efficiency power distribution in body control module PCBs.
Which built-in protection features of TPS1HA08AQPWPTQ1 allow it to replace discrete MOSFET plus protection circuits in a 24 V truck accessory switch?
The TPS1HA08AQPWPTQ1 integrates four protection functions: transient voltage clamping up to 40 V, over-current limiting with current sense output, thermal shutdown at approximately 150°C junction temperature, and under-voltage lockout. These four features replace the external Zener clamp, current sense resistor, comparator, and NTC thermistor that a discrete MOSFET-based solution requires, reducing BOM by at least 5 components while meeting AEC-Q100 Grade 0 automotive stress requirements.
For a body control module design, how does TPS1HA08AQPWPTQ1 compare to a 2-channel variant in terms of per-channel protection independence?
The TPS1HA08AQPWPTQ1 is a single-channel device in a 16-pin SOIC with dedicated over-current threshold and fault flag per switch. For BCM designs needing independent fault reporting per load, a single-channel device provides dedicated diagnostic output with the same 8 mΩ resistance and 40 V rating. Designers needing independent over-current thresholds on two separate loads should use two single-channel devices to maintain per-channel protection granularity rather than sharing a dual-channel part.
