Description
1
VS
Supply input voltage with internal clamp [typ. 15.6V]
2
RF
Oscillator timing resistor pin.
A buffer set alternatively to V
S
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)
3
CF
Oscillator timing capacitor pin.
A capacitor connected between this pin and GND fixes (together with R
F
) the oscillating
frequency
Alternatively an external logic signal can be applied to the pin to drive the IC.
4
GND
Ground
5
LVG
Low side driver output.
The output stage can deliver 170mA source and 270mA sink [typ.values].
6
OUT
Upper driver floating reference
7
HVG
High side driver output.
The output stage can deliver 170mA source and 270mA sink [typ.values].
8
BOOT
Bootstrap voltage supply.
It is the upper driver floating supply.
