SiP4613A, SiP4613B
Vishay Siliconix
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,
which is reduced to less than 1 µA. A flag output C_L is
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
6-pin PowerPAK^® TSC75-6 for operation over the industrial
temperature range of - 40 °C to 85 °C.
