Description

The High-side switch for memory card slot is an IC High-side switch with a function of over-current protection used in the power supply line of a memory card slot. In the switch part an N channel MOSFET low ON resistance has been 1 circuit integrated. Moreover, a soft start function, an under voltage lockout function and an over temperature protection function are integrated.
