The TPS272C45 is a dual-channel smart high-side switch designed to meet the requirements of industrial control systems. The low on-resistance (R DS(on) of 45 mΩ) minimizes device power dissipation driving a wide range (100 mA to 3 A) of output load current. The device provides an additional low voltage supply (3.3 V to 5 V) input pin to minimize no-load power dissipation. The device integrates protection features such as thermal shut down, output clamp, and overcurrent limit. These features improve system robustness during fault events such as short circuit.

The TPS272C45 device implements an adjustable threshold 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 implements a configurable inrush current time period with a higher level of allowed current to drive high inrush current loads like lamps or for fast charging of capacitive loads. The device also provides an accurate load current sense that allows for improved load diagnostics enabling better predictive maintenance.

The TPS272C45 device is available in a small 24-pin, 5 mm × 4 mm QFN leadless package with 0.5 mm pin pitch minimizing the PCB footprint.
