1.4 Device Information

The TPS1HC120-Q1 is a fully-protected single-channel, high-side power switch, with integrated NMOS power FET and charge pump.

Full diagnostics and high accuracy current sense features enable intelligent control of the load. Thermal shutdown behaviors as latch off or auto-retry are internally fixed in the part; please see the following and refer to the data sheet for more information.

  • TPS1HC120A-Q1: auto-retry
  • TPS1HC120B-Q1: latch
  • TPS1HC120C-Q1: hard-short auto-latch

The external programmable current limit feature improves system reliability by limiting inrush or overload current.
