High voltage half bridge driver with oscillator

Description

The device 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 device 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 assures a dead time to avoid crossconduction of the power devices. Two version are available: L6571A and L6571B. They differ in the internal dead time: 1.25μs and 0.72 μs (typ.)
