3 / 13 page 3/13 L6569 L6569A PIN FUNCTION ELECTRICAL CHARACTERISTCS (VS = 12V; VBOOT - VOUT = 12V; Tj = 25°C; unless otherwise specified.) N° Pin Description 1 VS Supply input voltage with internal clamp [typ. 15.6V] 2 RF 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 to drive a full H-bridge) 3 CF 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. 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. The bootstrap capacitor connected between this pin and pin 6 can be fed by an internal structure named “bootstrap driver” (a patented structure). This structure can replace the external bootstrap diode. Symbol Pin Parameter Test Condition Min. Typ. Max.
