SiP4612A/B
Vishay Siliconix
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
PowerPAK^® TSC75-6 for operation over the industrial
temperature range of - 40 °C to 85 °C.
