Vishay Siliconix
Protected 1-A High-Side Load Switch
APPLICATIONS
• Peripheral Ports
• Hot Swap
• Notebook Computers
• PDAs
DESCRIPTION
SiP4610A/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.
SiP4610A/B has a low quiescent current of 9 µA and in
shutdown the supply current is reduced to less than 1 µA.
In addition to current limit, the SiP4610A/B is protected by
undervoltage lockout and thermal shutdown.

There are two versions of the SiP4610. The SiP4610A has
an active low enable input, while the SiP4610B has an active
high enable input.
The SiP4610A/B is available in a lead (Pb)-free 5-pin thin
SOT-23 package for operation over the industrial
temperature range of - 40 to 85 °C.
