IR21141SSPBF Datasheet PDF - International Rectifier

●Description

●The IR21141/IR22141 gate driver family is suited to drive a single half bridge in power switching applications. These drivers provide high gate driving capability (2 A source, 3 A sink) and require low quiescent current, which allows the use of bootstrap power supply techniques in medium power systems. These drivers feature full short circuit protection by means of power transistor desaturation detection and manage all half-bridge faults by smoothly turning off the desaturated transistor through the dedicated soft shutdown pin, therefore preventing over-voltages and reducing electromagnetic emissions.

●Features

●• Floating channel up to 600 V or 1200 V

●• Soft over-current shutdown

●• Integrated desaturation detection circuit

●• Two stage turn on output for di/dt control

●• Separate pull-up/pull-down output drive pins

●• Matched delay outputs

●• Undervoltage lockout with hysteresis band

●• Lead free
