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.
