Self-oscillating Half-bridge Power IC
Features
Description
Integrated half-bridge 440V power MOSFET
GR6953 is a high voltage monolithic IC with
integrated 440V half-bridge power MOSFET.
Proprietary HVIC and latch immune CMOS
technologies enable ruggedized monolithic
Floating channel designed for bootstrap
operation
Noise immunity of transient voltage
Under-voltage lockout
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.
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)
