General Description

This is the product guarantees long time support in

Industrial market. The High-side switch, which has

over-current protection function, is used for the power

supply line of a memory card slot. In the switch part, an

N-channel MOSFET with low ON resistance has been 1

circuit integrated. The switch goes OFF when the

over-current

condition

lasts

longer

than

the

over-current shutdown time. The OFF switch is set to

latch off mode. The operating voltage range is 2.7V to

3.6V and the current limit value is set on 400mA, 1A.

Moreover, functions of soft start, under voltage lockout,

and over temperature protection are integrated.
