Protected 1-A High-Side Load Switch

DESCRIPTION

SiP4612A/B is a protected highside power switch. It is

designed to operate from voltages ranging from 2.4 V to

5.5 V and handle a continuous current of 1 A. The user

settable current limit protects the input supply voltage from

excessive load currents that might cause a system failure.

SiP4612A/B has a low quiescent current of 11 µA and in

shutdown the supply current is reduced to less than 1 µA.

In addition to current limit, the SiP4612A/B is protected by

undervoltage lockout and thermal shutdown.

The SiP4612A/B is available in a lead (Pb)-free 6-pin

temperature range of - 40 °C to 85 °C.
