3 Description

TPS1HTC30-Q1 is a single-channel, smart high-side

switch, with integrated NMOS power FET and charge

pump, designed to meet the requirements of 24-V

automotive battery systems. The low RON(30 mΩ)

minimizes device power dissipation driving a wide

range of output load current up to 6-A DC, and the 60-

V DC operating range improves system robustness.

The device integrates protection features such as

thermal shutdown, output clamp, and current limit.

These features improve system robustness during

fault events such as short circuit. TPS1HTC30-Q1

implements an adjustable current limiting circuit that

improves the reliability of the system by reducing

inrush current when driving large capacitive loads

and minimizing overload current. The device also

provides an accurate load current sense that allows

for improved load diagnostics such as overload

and open-load detection enabling better predictive

maintenance.

TPS1HTC30-Q1 is available in a small 14-pin, 4.40-

mm × 5.0-mm HTSSOP leaded package with 0.65-

mm pin pitch minimizing the PCB footprint.
