8 / 34 page 2 Pins description and connection diagrams L6722 8/34 9LGATE2 Channel 2 LS Driver Output. A small series resistor helps in reducing device-dissipated power. 10 LGATE3 Channel 3 LS Driver Output. A small series resistor helps in reducing device-dissipated power. 11 BOOT1 Channel 1 HS driver supply. Connect through a capacitor (100nF typ.) to PHASE1 and provide necessary Bootstrap diode. A small series resistor before the boot diode helps in reducing Boot capacitor overcharge. 12 UGATE1 Channel 1 HS driver output. A small series resistors helps in reducing device-dissipated power. 13 PHASE1 Channel 1 HS driver return path. It must be connected to the HS1 mosfet source and provides return path for the HS driver of channel 1. 14 BOOT2 Channel 2 HS driver supply. Connect through a capacitor (100nF typ.) to PHASE2 and provide necessary Bootstrap diode. A small series resistor before the boot diode helps in reducing Boot capacitor overcharge. 15 UGATE2 Channel 2 HS driver output. A small series resistors helps in reducing device-dissipated power. 16 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. 17 BOOT3 Channel 3 HS driver supply. Connect through a capacitor (100nF typ.) to PHASE3 and provide necessary Bootstrap diode. A small series resistor before the boot diode helps in reducing Boot capacitor overcharge. 18 UGATE3 Channel 3 HS driver output. A small series resistors helps in reducing device-dissipated power. 19 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. 20 N.C. Not Internally Bonded. 21 PGOOD Open Drain Output set free after SS has finished and pulled low when VSEN is lower than the relative threshold. Pull up to a voltage lower than 5V (typ), if not used it can be left floating. 22 N.C. Not Internally Bonded. Table 1. Pins description (continued) Pin# Name Function |
