IRS2336x(D) Family
Description
The IRS2336xD 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; the bootstrap diode functionality has been integrated into this device to reduce the
component count and the PCB size. 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.
