Automotive IC Automotive grade Gate driver AUIR3241S LOW QUIESCENT CURRENT BACK TO BACK MOSFET DRIVER Features Very low quiescent current on and off state Back to back configuration Product Summary Boost converter with integrated diode Standard level gate voltage Input active high and 3.3V compatible Operating voltage 3-36V Under voltage lockout with diagnostic Vgate 11.5V min. Wide operating voltage 3-36V I Vcc average On 45A max. at 25C Ground loss protection I Vcc average Off 35A max. at 25C Lead-Free, Halogen Free, RoHS compliant Applications Package Power switch for Stop and Start board net stabilizer Battery switch SO8 Description The AUIR3241S is a high side Mosfet driver for back to back topology targeting back to back switch. It features a very low quiescent current both on and off state. The AUIR3241S 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 controls the gate voltage. The AUIR3241S integrates an under voltage lock out protection to prevent to drive the Mosfet in linear mode.
