7 / 64 page ![]() L6713A Pin settings 7/64 2.2 Pin description Table 2. Pin description N° Pin Function 1UGATE1 Channel 1 HS driver output. A small series resistors helps in reducing device-dissipated power. 2BOOT1 Channel 1 HS driver supply. Connect through a capacitor (100 nF typ.) to PHASE1 and provide necessary Bootstrap diode. A small resistor in series to the boot diode helps in reducing Boot capacitor overcharge. 3 N.C. Not internally connected. 4 PHASE3 Channel 3 HS driver return path. It must be connected to the HS3 MOSFET source and provides return path for the HS driver of channel 3. 5UGATE3 Channel 3 HS driver output. A small series resistors helps in reducing device-dissipated power. 6BOOT3 Channel 3 HS driver supply. Connect through a capacitor (100 nF typ.) to PHASE3 and provide necessary Bootstrap diode. A small resistor in series to the boot diode helps in reducing Boot capacitor overcharge. 7 N.C. Not internally connected. 8 PHASE2 Channel 2 HS driver return path. It must be connected to the HS2 MOSFET source and provides return path for the HS driver of channel 2. Leave floating when using 2 phase operation. 9UGATE2 Channel 2 HS driver output. A small series resistors helps in reducing device-dissipated power. Leave floating when using 2 phase operation. 10 BOOT2 Channel 2 HS driver supply. Connect through a capacitor (100 nF typ.) to PHASE2 and provide necessary Bootstrap diode. A small resistor in series to the boot diode helps in reducing Boot capacitor overcharge.Leave floating when using 2 phase operation. 11 N.C. Not internally connected. 12 N.C. Not internally connected. 13 N.C. Not internally connected. 14 N.C. Not internally connected. 15 VCC Device supply voltage. The operative voltage is 12 V ±15 %. Filter with 1 µF (typ) MLCC vs. SGND. 16 PHASE_ SEL Phase selection pin. Internally pulled up by 12.5 µA(typ) to 5 V. It allows selecting between 2 phase and 3 phase operation. See Table 11 for details. |
