PRODUCTION DATA
When an output load is connected to the VM supply, the load current can be regulated to the ITRIP level. The ITRIP current level for OUT1 and OUT2 outputs is controlled by the VREF12 pin, and the ITRIP level for OUT3 and OUT4 outputs is controlled by the VREF34 pin. The ITRIP current can be calculated as ITRIP (A) = VREF (V) / 1.32 (V/A). The VREF voltage can be programmed by connecting resistor dividers from DVDD pin to ground. Both VREF pins can be tied together to program the same ITRIP current for all four output channels.
