Infineon – AUIR3242S – High side gate driver for 12V power distribution applications

AUIR3242SXUMA1

AUIR3242S is perfect for applications that require very low on state operation current to support key-off loads. This feature is called idle mode. Idle mode results in gate driver operation current that is as less than 50 μA. Idle mode is unique on the market for gate drivers in this power class and plays a big role in increasing efficiency in hybrid electric vehicles. AUIR3242S has a high level active input which supports direct drive from battery.

Features
– Idle mode (50μA quiescent current)
– Boost converter with integrated diode
– Support of back to back architectures
– Wide operating voltage 3-36V
– Ground loss protection
– Gate current monitoring via frequency
– Undervoltage lockout with diagnostics
