Product Details

TPS4H160BQPWPRQ1 combines four Texas Instruments automotive high-side switch channels and 160 mΩ integrated FETs in a 28-pin PWP thermal package.

The channels distribute power to several independent vehicle loads, and an externally selected current limit helps cap starting or fault current before it propagates through the supply network.

This B ordering variant provides analog current sense, allowing a controller to monitor load current and detect a drift in behavior in addition to reading fault conditions.

Short-to-ground, open-load and short-to-battery diagnostics support harness troubleshooting, while the negative-voltage clamp gives inductive loads a controlled turn-off path.

The four outputs and larger package distinguish this option from the two-channel TPS2H160B, so board area and channel count can be weighed together.
