PINTYPE(1)DESCRIPTION
NO.NAME
F3ACDRV1PInput 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.
F2ACDRV2PInput 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.
E6BATN_SRPAINegative 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.
F6BATPAIPositive input for battery voltage sensing - Connect to positive terminal of battery pack. Place 100-Ω series resistance between pin and positive terminal.
D1CDRVHAIOCharge pump for gate drive - Connect a 0.22-µF cap between CDRVH and CDRVL_ADDRMS.
E1CDRVL_ADDRMSAIOCharge 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, B4CFH1PSwitched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFL1.
C4, D4CFH2PSwitched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFL2.
A2, B2CFL1PSwitched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFH1.
C2, D2CFL2PSwitched cap flying cap connection -Connect 1 to 3 22-µF caps in parallel between this pin and CFH2.
D5INTDOOpen 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.
A1, B1, C1GNDPGround return
A5, B5, C5PMIDPInput to the switched cap power stage -Connect 10-µF cap to PMID.
F1REGNAOCharger 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.
E5SCLDII2C interface clock - Pull up to 3.3 V with 10-kΩ resistor.
F5SDADIOI2C interface data - Pull up to 3.3 V with 10-kΩ resistor.
D6SRN_SYNCINAINegative 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.
E4TSBAT_SYNCOUTAIBattery 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.
F4TSBUSAIBUS temperature voltage input - Requires external resistor divider, NTC, and voltage reference. See the TSBUS section for choosing the resister divider values.
A6, B6, C6VBUSPDevice power input - Connect 1-µF capacitor from VBUS to GND.
