5 / 44 page ![]() L6701 2 Pins description and connection diagrams 5/44 2 Pins description and connection diagrams Figure 1. Pins connection (Top view) 2.1 Pin description Table 1. Pins description Pin n ° Name Function 1SGND All the internal references are referred to this pin. Connect to the PCB Signal Ground. 2VCC Device Power Supply and LS driver supply. Operative voltage is 12V ±15%. Filter with at least 1 µF MLCC vs. ground. 3LGATE1 Channel 1 LS Driver Output. A small series resistor helps in reducing device-dissipated power. 4 PGND LS Drivers return path. Connect to Power ground Plane. 5LGATE2 Channel 2 LS Driver Output. A small series resistor helps in reducing device-dissipated power. 6LGATE3 Channel 3 LS Driver Output. A small series resistor helps in reducing device-dissipated power. 7 BOOT1 Channel 1 HS driver supply. Connect through a capacitor (100nF typ.) to PHASE1 and provide necessary Bootstrap diode. A small series resistor upstream the boot diode helps in reducing Boot capacitor overcharge. 8UGATE1 Channel 1 HS driver output. A small series resistors helps in reducing device-dissipated power. 9 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. 21 22 23 24 25 26 27 28 29 30 31 32 1 2 3 4 5 6 7 8 9 10 11 12 VID0 VID5 FBR FBG ISEN3 ISEN2 ISEN1 CS+ CS- VSEN FB COMP PHASE2 UGATE2 BOOT2 PHASE1 UGATE1 BOOT1 LGATE3 LGATE2 PGND LGATE1 VCC SGND 19 20 VID4 VID3 VID2 VID1 13 14 15 16 SSEND / PGOOD PHASE3 UGATE3 BOOT3 17 18 OSC / EN / FAULT DAC_SEL REF_IN REF_OUT 33 34 35 36 |
