Product Details

TPS1H100AQPWPRQ1 is the A-version, single-channel automotive high-side switch in a 14-pin PWP HTSSOP package, combining an NMOS power FET with control and protection circuits.

Its 5-to-40-V nominal operating span extends down to 3.5 V with increased on resistance; the typical resistance is 80 milliohms at 25 degrees C and supplies above 5 V.

An external resistor sets the current limit, so inrush and short-circuit behavior can be matched to the wiring and load instead of relying on a fixed threshold.

The A variant reports faults through an open-drain status pin, unlike the B variant's analog current-sense output, making the MCU interface a decisive ordering-code difference.

Overload detection and thermal shutdown protect the switch, while the specified -40-to-125-degree-C ambient range bounds automotive operation.
