Description
Self-oscillating 600 V half-bridge driver IC with typical 0.18 A source and 0.26 A sink current in 8-pin SOIC package for IGBTs and MOSFETs. Also available in an 8-pin PDIP package. characteristic • Integrated 600 V half-bridge gate driver • 15.6 V Zener clamp on Vcc • True micropower start-up • Tighter control of initial dead time • Dead time at low temperature coefficient • Off on CT pin off characteristics (1/6th Vcc) • Increased undervoltage lockout hysteresis (1 V) • Level shifter circuit for lower power consumption • Constant LO, HO pulse width at start-up • Lower di/dt gate driver available Better Noise Immunity • High side output in phase with RT • Excellent lock-in noise immunity on all inputs and outputs • ESd protection on all pins Advantages: • Integrated 600V half-bridge gate driver • 15.6 on Vcc V Zener Clamp • True micropower start-up • Tighter control of initial deadtime • Deadtime at low temperature coefficient • Shutdown feature on CT pin (1/6th Vcc) • Increased undervoltage lockout hysteresis (1V) • Lower power level shifting circuit • Constant LO, HO pulse width at startup • Lower di/dt gate driver for better noise immunity • High side output in phase with RT • Internal 50nsec (Typical) Bootstrap Diode (IR21531D) • Excellent Lock-in Immunity on All Inputs and Outputs • ESd Protection on All Pins • Also available in lead-free package All the evaluation(0)
