TPS281C100 is a single channel smart high-side switch designed to meet the requirements of industrial control systems. The low RON minimizes device power dissipation, driving a wide range of output load current up to 60V DC operation 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. TPS281C100 implements an adjustable current limiting circuit that improves system reliability 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, TPS281C100A 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.
TPS281C100 is available in a small 14-pin, 4.4mm × 5mm HTSSOP leaded package with 0.65mm pin pitch and 12-pin, 4mm × 4mm WSON with 0.5mm pin pitch minimizing the PCB footprint.
