International Rectifier IR2131(J)(S) High Side and Low Side Driver Datasheet
The International Rectifier IR2131(J)(S) is a high voltage, high speed power MOSFET and IGBT driver featuring three independent high and low side referenced output channels. It utilizes proprietary HVIC technology for ruggedized monolithic construction and includes logic inputs compatible with CMOS or LSTTL outputs down to 2.5V.
The device features floating channels designed for bootstrap operation, fully operational up to +600V VOFFSET. Key characteristics include tolerance to negative transient voltage, a gate drive supply range from 10 to 20V, undervoltage lockout for all channels, and an over-current shutdown function that turns off all six drivers.
