AUIRS2336S_15 Datasheet, PDF (3/37 Pages) International Rectifier – Drives up to six IGBT/MOSFET power devices

AUIRS2336S
Description
The AUIRS2336S are high voltage, high speed, power MOSFET and IGBT gate drivers with three high-side and
three low-side referenced output channels for 3-phase applications. This IC is designed to be used with low-cost
bootstrap power supplies. Proprietary HVIC and latch immune CMOS technologies have been implemented in a
rugged monolithic structure. The floating logic input is compatible with standard CMOS or LSTTL outputs (down
to 3.3 V logic). A current trip function which terminates all six outputs can be derived from an external current
sense resistor. Enable functionality is available to terminate all six outputs simultaneously. An open-drain
FAULT signal is provided to indicate that a fault (e.g., over-current, over-temperature, or undervoltage shutdown
event) has occurred. Fault conditions are cleared automatically after a delay programmed externally via an RC
network connected to the RCIN input. The output drivers feature a high-pulse current buffer stage designed for
minimum driver cross-conduction. Shoot-through protection circuitry and a minimum deadtime circuitry have
been integrated into this IC. Propagation delays are matched to simplify the HVIC’s use in high frequency
applications. The floating channels can be used to drive N-channel power MOSFETs or IGBTs in the high-side
configuration, which operate up to 600 V.
