(*)
The device has an internal zener clamp between GND and V^_S (typical 15.6V).
Therefore the circuit should not be driven by a DC low impedance power source.

Note: ESD immunity for pins 6, 7 and 8 is guaranteed up to 900 V (Human Body Model)


Description

The L6571B is a high voltage half bridge driver with built-in oscillator. The frequency of the L6571B can be programmed using external resistor and capacitor.

The output drivers are designed to drive external n-channel power MOSFET and IGBT. The internal logic assures a minimum dead time to avoid cross-conduction of the power devices.
