Pin connection
Pin description
Supply input voltage with internal clamp [typ. 15.6V]
Oscillator timing resistor pin. A buffer set alternatively to VS and GND can provide
current to the external resistor RF 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 RF) the oscillating 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].
