Infineon Technologies AUIR3240S Low Quiescent Current MOSFET Driver

Infineon introduces the automotive-qualified AUIR3240S battery power switch for the combustion-engine shut-off and restarts function (Stop-Start system) that can help reduce fuel consumption in automotive vehicles by up to 15 percent. The Infineon AUIR3240S Low Quiescent Current MOSFET Driver is a combination of a boost DC/DC converter with an external inductor and a gate driver. The device drives standard level MOSFET even at low battery voltage and is capable of driving several MOSFETs in parallel to achieve very low on-state resistance (Rds(on)) with a current consumption below 50µA. AUIR3240S provides 15V on the output with a wide 4V to 36V input voltage. In addition, AUIR3240S features diagnostic on the output current and a thermal sensor interface.
