3 Description

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.
