Automotive, 60-V, 6-A, 30-mΩ, one-channel smart high-side switch with adjustable current limit
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.
