Functional safety capable

TPS281C30x is a single channel smart high-side

switch designed to meet the requirements of industrial

control systems. The low R_ON(30 mΩ) minimizes

device power dissipation, driving a wide range of

output load current up to 6-A DC and the 64-V DC

tolerance improves system robustness.

The device integrates protection features such as

thermal shut down, output clamp, and current limit.

These features improve system robustness during

fault events such as short circuit. TPS281C30x

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. In order to drive

high inrush current loads such as lamps or fast

charging capacitive loads, TPS281C30x 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.
