Protected 1-A High-Side Load Switch

DESCRIPTION

SiP4613A, SiP4613B 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.

SiP4613A, SiP4613B has a low shutdown supply current,

available to indicate fault conditions such as output short

and thermal protection.

In addition to current limit, the SiP4613A, SiP4613B is

protected by undervoltage lockout and thermal shutdown.

The SiP4613A, SiP4613B is available in a lead (Pb)-free

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