tor. The internal circuitry of the device allows it to be

driven also by external logic signal.

The output drivers are designed to drive external n-

channel power MOSFET and IGBT. The internal log-

ic assures a dead time to avoid cross-conduction of

the power devices.

Two version are available: L6571A and L6571B.

They differ in the internal dead time: 1.25碌s and

0.72碌s (typ.)

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 capaci-
