Data Sheet ADP5091/ADP5092 Pin No.1 ADP5091 ADP5092 Mnemonic Description
19 19 PGOOD Output Signal to Microcontroller. This pin maintains a pulled high level when SYS is higher than the SETPG threshold. 20 20 VID Voltage Configuration Pin for REG_OUT. This pin sets up to eight different regulated outputs tied low through a resistor to AGND. The output configuration details are in Table 7. 21 21 MINOP Minimum Operating Power. Place a resistor on MINOP to set the minimum operating input voltage level. The boost regulator starts switching when the CBP voltage exceeds the MINOP voltage. When the MINOP pin is floating, the IC operates in no sensing mode with a fixed MPPT level. Connect this pin through AGND to disable the MINOP function. 22 22 DIS_SW Control Signal from Microcontroller or RF Transceiver to Stop Switching Boost Charger. 23 23 REG_D1 Regulated Output Working Mode Set D1. Enable LDO mode by pulling this pin high. 24 24 REG_D0 Regulated Output Working Mode Set D0. Enable boost mode by pulling this pin high. EPAD Exposed Pad. The exposed pad must be connected to AGND. 1 N/A means not applicable. Rev.
