Description
TS19706 is a high voltage, high speed, 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 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.
