Product Summary
The L6569A is a high voltage half bridge driver with built in oscillator. The frequency of the oscillator can be programmed using external resistor and capacitor. The internal circuitry of the L6569A allows it to be driven also by external logic signal. The output drivers are designed to drive external nchannel power MOSFET and IGBT. The internal logic of the L6569A assures a dead time [typ. 1.25ms] to avoid crossconduction of the power devices.
