3 Description
The TPS7H2211-SP 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 4.5 V to 14 V and supports a maximum
continuous current of 3.5 A.
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-SP is available in a ceramic package
with an exposed thermal pad allowing for improved
thermal performance.
