1 VDD1 Power Supply for the Side 1 Logic Circuits of the Device. It is independent of VDDP and can operate between 3.135 V and 5.5 V. 2, 5, 6, 10 GNDP Ground Reference for Isolator Side 1. All of these pins are internally connected, and it is recommended that all GNDP pins be connected to a common ground. 3 VOA Logic Output A. 4 VOB Logic Output B. 7, 14 NC This pin is not connected internally (see Figure 5). 8 PDIS Power Disable. When this pin is tied to a logic low, the power converter is active; when tied to a logic high, the power supply enters a low power standby mode. 9 VDDP Primary isoPower Supply Voltage, 3.135 V to 5.5 V. 11, 15, 16, 19 GNDISO Ground Reference for Isolator Side 2. All of these pins are internally connected, and it is recommended that all GNDISO pins be connected to a common ground. 12 VISO Secondary Supply Voltage Output for External Loads, 3.3 V (VSEL Low) or 5.0 V (VSEL High). 13 VSEL Output Voltage Select. Provide a thermally matched resistor network between VISO and GNDISO to divide the required output voltage to match the 1.25 V reference voltage. VISO voltage can be programmed up to 20% higher or 75% lower than VDDP but must be within the allowed output voltage range. 17 VIB Logic Input B. 18 VIA Logic Input A. 20 VDD2 Power Supply for the Side 2 Logic Circuits of the Device. It is independent of VISO and can operate between 3.135 V and 5.5 V. Rev.
