IRS26302DJ
Description
The IRS26302DJPBF are high voltage, high speed power MOSFET and IGBT drivers with three independent high
and low side referenced output channels for 3-phase applications. An additional low side driver is included for PFC
or Brake IGBT driving operation. Proprietary HVIC technology enables rugged monolithic construction. Logic inputs
are compatible with CMOS or LSTTL outputs, down to 3.3V logic. Three current trip functions that terminate all
seven outputs can be derived from three external shunt resistors. Each overcurrent trip functions consists of
detecting excess current across a shunt resistor on DC+ bus, on DC- bus and on Brake or PFC circuitry. An enable
function is available to terminate all outputs simultaneously and is provided through a bidirectional pin combined
with an open-drain FAULT pin. Fault signal is provided to indicate that an overcurrent or undervoltage shutdown
has occurred. Overcurrent fault conditions are cleared automatically after an externally programmed delay via an
RC network connected to the RCIN input. A diagnostic feature can give back to the controller the fault cause
(UVcc, DC- or DC- overcurrent) and address a fault register. The output drivers feature a high pulse current buffer
stage. Propagation delays are matched to simplify use in high frequency applications designed for minimum driver
cross conduction. The floating channel can be used to drive N-channel power MOSFET’s or IGBT’s in the high
side configuration which operates up to 600 V.
