IR21141SSPBF

Product Summary

The IR21141SSPBF gate driver is suited to drive a single half bridge in power switching applications. The driver provides 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. The IR21141SSPBF features 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.
