TPS281C30x is a single channel smart high-side switch designed to meet the requirements of industrial control systems. The low RON (30mΩ) minimizes device power dissipation, driving a wide range of output load current up to 6A DC and the 64V 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.
TPS281C30E provides enhanced Electrical Fast Transient (EFT) immunity, where the device will stay off with up to 2.5kV EFT pulse applied at VS or VOUT, 10nF output capacitor and 100pF coupling capacitor between the pulse generator and the output. The EFT level can be further increased if a larger output capacitor is used. The enhanced EFT immunity improves the system’s robustness against undesired coupling in the industrial systems.
TPS281C30x is available in a small 14-pin, 4.4mm × 5mm HTSSOP leaded package (version A, B, C, D) with 0.65mm pin pitch and 20-pin, 5mm × 5mm QFN with 0.65mm pin pitch (all versions) minimizing the PCB footprint.
