This datasheet provides information about the IR2131, a high voltage, high speed power MOSFET and IGBT driver with three independent high and low side referenced output channels. The device employs proprietary HVIC technology and features a ruggedized monolithic construction. Logic inputs are compatible with 5V CMOS or LSTTL outputs. An external current sense resistor can be used to generate a current trip function that terminates all six outputs. A shutdown input is provided for a customized shutdown function. An open drain FAULT signal is also provided to indicate that any of the shutdowns have 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.
The IR2131 is a high voltage, high speed power MOSFET and IGBT driver with three independent high and low side referenced output channels. It utilizes proprietary HVIC technology for ruggedized monolithic construction and is fully operational to +600V. The device includes a current trip function for over-current shutdown and an open drain FAULT signal to indicate shutdown conditions.
The driver features floating channels designed for bootstrap operation, allowing it to drive N-channel power MOSFETs or IGBTs in the high side configuration. Logic inputs are compatible with 5V CMOS or LSTTL outputs, and the device includes undervoltage lockout for all channels. Propagation delays are matched across all channels to simplify use in high frequency applications.
