NO. | NAME | |||
F3 | ACDRV1 | P | Input FETs Driver Pin 1 - The charge pump output to drive the port #1 input N-channel MOSFET (ACFET1) and the reverse blocking N-channel MOSFET (RBFET1). ACDRV1 voltage becomes 5 V above the common drain connection of the ACFET1 and RBFET1, when the turn-on condition is met. If ACFET1 and RBFET1 are not used, connect ACDRV1 to ground. | |
F2 | ACDRV2 | P | Input FETs Driver Pin 2 -The charge pump output to drive the port #2 input N-channel MOSFET (ACFET2) and the reverse blocking N-channel MOSFET (RBFET2). ACDRV2 voltage becomes 5 V above the common drain connection of the ACFET2 and RBFET2, when the turn-on condition is met. If ACFET2 and RBFET2 are not used, connect ACDRV2 to ground. | |
E6 | BATN_SRP | AI | Negative input for battery voltage sensing and positive input for battery current sensing- Connect to negative terminal of battery pack. It is also used for battery current sensing. Place RSNS (2 mΩ or 5 mΩ) between BATN_SRP and SRN_SYNCIN. Short BATN_SRP to SRN_SYNCIN together and place 100-Ω series resistance between pin and negative terminal if RSNS is not being used. | |
F6 | BATP | AI | Positive input for battery voltage sensing - Connect to positive terminal of battery pack. Place 100-Ω series resistance between pin and positive terminal. | |
D1 | CDRVH | AIO | Charge pump for gate drive - Connect a 0.22-µF cap between CDRVH and CDRVL_ADDRMS. | |
E1 | CDRVL_ADDRMS | AIO | Charge pump for gate drive - Connect a 0.22-µF cap between CDRVH and CDRVL_ADDRMS. During Power ON Reset (POR), this pin is used to assign the address of the device and the mode of the device as Standalone, Primary, or Secondary. | |
A4, B4 | CFH1 | P | Switched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFL1. | |
C4, D4 | CFH2 | P | Switched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFL2. | |
A2, B2 | CFL1 | P | Switched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFH1. | |
C2, D2 | CFL2 | P | Switched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFH2. | |
D5 | INT | DO | Open drain, active low interrupt output - Pull up to voltage with 10-kΩ resistor. Normally high, the device asserts low to report status and faults. INT is pulsed low for tINT. | |

F1 | REGN | AO | Charger internal LDO output - Connect a 4.7-µF cap between this pin and GND. When in Primary/Secondary Mode, connect through 1-kΩ resistor to the TSBAT_SYNCOUT and SRN_SYNCIN pins. Do not use REGN for any other function. | |
E5 | SCL | DI | I2C interface clock - Pull up to 3.3 V with 10-kΩ resistor. | |
F5 | SDA | DIO | I2C interface data - Pull up to 3.3 V with 10-kΩ resistor. | |
D6 | SRN_SYNCIN | AI | Negative input for battery current sensing - Place RSNS (2 mΩ or 5 mΩ) between SRN_SYNCIN and SRP. Short to SRP and SRN_SYNCIN together if not used. If configured as a secondary for dual charger configuration, this pin functions as SYNCIN, and connect to TSBAT_SYNCOUT of Primary, and connect a 1-kΩ pullup resistor to REGN. | |
E4 | TSBAT_SYNCOUT | AI | Battery temperature voltage input and Primary Mode SYNCOUT - Requires external resistor divider, NTC, and voltage reference. See the TSBAT section for choosing the resister divider values. If the device is in Primary Mode, connect this pin to SRN_SYNCIN of the Secondary device. | |
