This half-bridge gate driver IC operates up to 600 V and provides typical 1.9 A source and 2.3 A sink drive capability for MOSFET and IGBT stages. It uses a functional level-shift junction-isolated architecture with programmable deadtime, two channels, and a 10 V to 20 V gate-drive supply range. Industrial qualification, turn-on and turn-off propagation delays of 180 ns and 220 ns, and VBS and VCC undervoltage lockout thresholds of 8.9 V on and 8.2 V off are specified on the product page. The verified orderable variant is supplied in a 14-pin SOIC package and is lead-free, halogen-free, and RoHS compliant.
