GR6953

GR6953 Self-oscillating Half-bridge Power IC Features ● Integrated half-bridge 440V power MOSFET ● Floating channel designed for bootstrap operation ● Noise immunity of transient voltage ● Under-voltage lockout ● Programmable oscillator frequency ● Matched propagation delay for both channels ● Ultra low startup current of 75uA ● Shutdown function turns off both channels ● Low side output in phase with RT Applications ● Compact fluorescent lamps (CFL) ● Cathode compact fluorescent lamp (CCFL) Description GR6953 is a high voltage monolithic IC with integrated 440V half-bridge power MOSFET. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The front end features a programmable oscillator which is similar to the 555 timer. The output drivers feature a high pulse current buffer stage and an internal dead time designed for minimum driver cross-conduction. Propagation delays for the two channels are matched to simplify use in 50% duty cycle applications.
