The TPS7H2201 is a single channel eFuse that provides configurable rise time to minimize inrush current and reverse current protection. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.5V to 7V and can support a maximum continuous current of 6A. The switch is controlled by an on and off input (EN), which is capable of interfacing directly with low-voltage control signals.

The TPS7H2201 is available in a ceramic and plastic package with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –55°C to 125°C.
