3 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.
