3 Description

The TPS7H2211 is a single channel eFuse (integrated

FET load switch with additional features) that provides

reverse current protection, overvoltage protection, and

a configurable rise time to minimize inrush current,

soft start. The device contains P-channel MOSFETs

that operate over an input voltage range of 4.5V to

14V and supports a maximum continuous current of

3.5A.

The switch is controlled by an on and off input

(EN), which is capable of interfacing directly with

low-voltage control signals. Overvoltage protection

and soft start are programmable with few external

components through the OVP and SS pins. The

TPS7H2211 is available in a ceramic and plastic

package with an exposed thermal pad allowing

for improved thermal performance. A standard

microcircuit drawing (SMD) is available for the QML

5962R1822001VXC. A vendor item drawing (VID) is

available for the -SEP variant, V62/23609.
