IR2131
3 HIGH SIDE AND 3 LOW SIDE DRIVER
Features
n Floating channel designed for bootstrap operation
Fully operational to +600V
Tolerant to negative transient voltage
dV/dt immune
n Gate drive supply range from 10 to 20V
n Undervoltage lockout for all channels
n Over-current shutdown turns off all six drivers
n Independent 3 high side & 3 low side drivers
n Matched propagation delay for all channels
n Outputs out of phase with inputs
Description
The IR2131 is a high voltage, high speed power
MOSFET and IGBT driver with three independent high
and low side referenced output channels. Proprietary
HVIC technology enables ruggedized monolithic
construction. Logic inputs are compatible with 5V
CMOS or LSTTL outputs. A current trip function which
terminates all six outputs can be derived from an
external current sense resistor. A shutdown input is
provided for a customized shutdown function. An open
drain FAULT signal is provided to indicate that any of
the shutdowns has occurred. The output drivers
feature a high pulse current buffer stage designed for
minimum driver cross-conduction. Propagation delays
are matched to simplify 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 volts.
