Applications

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.
