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

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 R_T

Applications

Compact fluorescent lamps (CFL)

Cathode compact fluorescent lamp (CCFL)
