GR8853  
Self-oscillating Half-bridge Driver  
Features  
Description  
GR8853 is  
a
high voltage, high speed,  
Floating channel designed for bootstrap  
self-oscillating power MOSFET and IGBT driver  
with both high and low side referenced output  
channels. Proprietary HVIC and latch immune  
CMOS technologies enable ruggedized monolithic  
operation to +600V  
Noise immunity of transient voltage  
Under-voltage lockout  
Programmable oscillator frequency  
Matched propagation delay for both channels  
Ultra low startup current of 75uA  
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. The floating channel can be used to  
drive an N-MOSFET or IGBT in the high side  
configuration that operates off a high voltage rail  
up to 600 volts.  
Shutdown function turns off both channels  
Low side output in phase with RT  
Applications  
HID lamp ballast  
PDP sustain driver  
Motor driver  
SMPS  
Ordering and Marking Information
