Description for the TPS1HC100-Q1The TPS1HC100-Q1 device is a fully protected high-side power
switch, with integrated NMOS power FET and charge pump, targeted
for the intelligent control of various loads. Accurate current
sense and programmable current limit features differentiate it from
the market. Low logic high threshold, VIH, of 1.5 V on the input pins allow use
of MCUs GPIO signals to 1.8 V. High-accuracy current sensing
provides a better real-time monitoring effect and more accurate
diagnostics without further calibration. The external high-accuracy
current limit allows setting the current limit value by
application. The device highly improves the reliability of the
system by effectively clamping the inrush current under start-up or
short-circuit conditions. The TPS1HC100-Q1 device can be used as a
high-side power switch for a wide variety of resistive, inductive,
and capacitive loads, including low-wattage bulbs, LEDs, relays,
solenoids, and heaters. |
