    Description

    The TPS7H2201-SP is a single channel load switch 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 1.5 V to 7 V and can support a maximum continuous current of 6 A. The switch is controlled by an on and off input (EN), which is capable of interfacing directly with low-voltage control signals.

    The TPS7H2201-SP is available in a ceramic 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.
