The Texas Instruments TPS4H160BQPWPRQ1 is a quad-channel smart high-side power switch rated to 40 V with approximately 160 mΩ of on-resistance per channel, supplied in a 28-pin HTSSOP with a thermal pad. It operates from a 4 V to 40 V supply, drives four independent outputs at up to 2.5 A, and draws about 8 mA of supply current. The TPS4H160BQPWPRQ1 is rated for -40°C to 125°C ambient with a 150°C maximum junction temperature, and switches on and off in roughly 50 µs.

Smart high-side switches replace mechanical relays and discrete MOSFET-plus-driver circuits for switching loads referenced to ground, adding integrated protection and diagnostics so the controller learns about a fault instead of just losing the load. A four-channel device with a 40 V rating and 2.5 A capability fits 12 V and 24 V load-switching duty for lamps, LED strings, solenoids, valves, small motors, and resistive heaters. Typical designs are body and lighting control modules, industrial and building I/O modules, and digital output cards where several loads are driven from one board. Buyers are automotive and industrial equipment OEMs and their contract manufacturers.
