7 / 70 page ![]() L6714 Pin settings 7/70 2.2 Functions Table 1. Pin functions 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 (100nF 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 (100nF 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. 9UGATE2 Channel 2 HS driver output. A small series resistors helps in reducing device-dissipated power. 10 BOOT2 Channel 2 HS driver supply. Connect through a capacitor (100nF typ.) to PHASE2 and provide necessary Bootstrap diode. A small resistor in series to the boot diode helps in reducing Boot capacitor overcharge. 11 N.C. Not internally connected. 12 PHASE4 Channel 4 HS driver return path. It must be connected to the HS4 mosfet source and provides return path for the HS driver of channel 4. 13 UGATE4 Channel 4 HS driver output. A small series resistors helps in reducing device-dissipated power. 14 BOOT4 Channel 4 HS driver supply. Connect through a capacitor (100nF typ.) to PHASE4 and provide necessary Bootstrap diode. A small resistor in series to the boot diode helps in reducing Boot capacitor overcharge. |
