PHASE1 UGATE1 BOOT1 BOOT2 UGATE2 PHASE2 VCCDR2 LGATE2 PGND2 VCCDR3 N.C. L6711 Table 1. Pins description N° Name Description 1 VCCDR1 Channel 1 LS driver supply: it can be varied from 5V to 12V buses. It must be connected together with other VCCDRx pins. Filter locally with at least 1 µF ceramic cap vs. PGND1. 2LGATE1 Channel 1 LS driver output. A little series resistor helps in reducing device-dissipated power. 3 PGND1 Channel 1 LS driver return path. Connect to Power Ground Plane. 4VCC Device supply voltage. The operative supply voltage is 12V ±15%. Filter with 1 µF capacitor (Typ.) vs. SGND. 5 SGND All the internal references are referred to this pin. Connect it to the PCB signal ground. 6 OFFSET Offset programming pin, internally fixed at 1.240V. Short to SGND to disable the offset generation or connect through a resistor ROFFSET to SGND to program an offset (positive or negative, depending on TC status) to the regulated output voltage as reported in the relative section. 7COMP This pin is connected to the error amplifier output and is used to compensate the control feedback loop. |
