Description
General part information
AUIR3242 Series
The AUIR3242S 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 AUIR3242S 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 AUIR3242S integrates an under voltage lock out protection to prevent to drive the Mosfet in linear mode. AUIRS3241Sand AUIR3242S are basically identical, only difference is the operating level of the input pin. For instance, due to the active low level of input the AUIR3242S makes relay replacement very easy. The AUIRS3241S can be driven directly from the battery voltage. By connecting the Input Pin to ground this gate driver IC together with the Infineon OptiMOS™ MOSFETs could be used for reverse battery protection.
