1.4 Device Information

TPS1HTC100-Q1

This device is the device under evaluation by using this EVM. TPS1HTC100-Q1 is a single channel smart high-side switch designed to meet the requirements of 24V automotive battery systems. The 83mΩ RON minimizes device power dissipation driving a wide range of output load current up to 4A DC and the 60V DC tolerance improves system robustness.

These features improve system robustness during fault events such as short circuit. TPS1HTC100-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. To drive high inrush current loads such as lamps or fast charging capacitive loads, TPS1HTC100-Q1 implements an inrush current time period with a higher level of allowed 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.

TPS1HTC100-Q1 is available in a small 14-pin, 5.0mm × 6.4mm HTSSOP leaded package with 0.65mm pin pitch minimizing the PCB footprint.
