Internal Dead Time
Supply input voltage with internal clamp [typ. 15.6V]
Oscillator timing resistor pin.
A buffer set alternatively to V
connected between pin 2 and 3.
Alternatively, the signal on pin 2 can be used also to drive another IC (i.e. another L6569/71 to
drive a full H-bridge)
Oscillator timing capacitor pin.
A capacitor connected between this pin and GND fixes (together with R
frequency
Alternatively an external logic signal can be applied to the pin to drive the IC.
Ground
Low side driver output.
The output stage can deliver 170mA source and 270mA sink [typ.values].
Upper driver floating reference
High side driver output.
The output stage can deliver 170mA source and 270mA sink [typ.values].
Bootstrap voltage supply.
It is the upper driver floating supply.
