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.
