Product Details

TPS4H000AQPWPRQ1 is Texas Instruments' four-channel automotive high-side switch for modest-current loads, packaged as a 20-pin thermally enhanced PWP device.

Each integrated 1 Ω path can switch a separate load, reducing the need for four discrete driver and protection circuits when a controller has several low-current outputs.

An external current-limit resistor and thermal shutdown contain overload faults, while the internal clamp handles the negative voltage generated when an inductive load is turned off.

The A variant returns open-drain status rather than the analog current-sense signal of version B, which suits systems that need fault interrupts without continuous load-current measurement.

Open-load and short-to-battery detection remain available for wire diagnosis across the automotive grade 1 ambient range.
