Description
The AUIR3240S is a high side mosfet driver for battery
switch application where a very low quiescent current is
required when the driver is on. The AUIR3240S is a
combination of a boost DC/DC converter using an external
inductor and a gate driver. It drives standard level Mosfet
even at low battery voltage. The input is active low to
reduce current consumption.
