Name Type Function 5 LVG O Low Side Driver Output: the output stage can deliver 400mA source and 650mA sink [Typ. Values]. The circuit guarantees 0.3V max on the pin (@ Isink = 10mA) with VCC > 3V and lower than the turn on threshold. This allows to omit the bleeder resistor connected between the gate and the source of the external mosfet normally used to hold the pin low; the gate driver ensures low impedance also in SD conditions. 6 Vout O Upper Driver Floating Reference: layout care has to be taken to avoid below ground spikes on this pin. 7 HVG O High Side Driver Output: the output stage can deliver 400mA source and 650mA sink [Typ. Values]. The circuit gurantees 0.3V max between this pin and Vout (@ Isink = 10mA) with VCC > 3V and lower than the turn on threshold. This allows to omit the bleeder resistor connected between the gate and the source of the external mosfet normally used to hold the pin low; the gate driver ensures low impedance also in SD conditions. 8 Vboot Bootstrap Supply Voltage: 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. PIN DESCRIPTION (continued) L6384 3/10 |
