The AUIR3242S is a high side Mosfet driver for back to back topology targeting back to back switch

Infineon AUIR324x family product picture

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.

 

Key features

  • Idle Mode (<50µA quiescent current) - on and off state
  • Support for LV124 cold cranking standards
  • Standard level gate voltage
  • Input active high and 3.3V compatible

 

Additional features

  • Wide operating voltage 3-36V
  • Boost converter with integrated diode
  • Support for back to back and Q-diode applications
  • Under voltage lockout with diagnostics
  • Loss of ground protection
  • Gate current monitoring via frequency
  • Over-temperature protection via NTC

 

Applications

  • Relay Replacement
  • DC/DC safety switch
  • board net stabilization
