BQ76907RGRR from TEXAS INSTRUMENTS, in a VQFN-20-EP(3.5x3.5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VC4 | input | Voltage-sense input for the fourth cell from the bottom of the stack; it also supplies cell-balancing current for that cell and returns balancing current for the fifth cell. |
| 2 | VC3 | input | Voltage-sense input for the third cell from the bottom of the stack; it also supplies cell-balancing current for that cell and returns balancing current for the fourth cell. |
| 3 | VC2 | input | Cell sense input for the second cell from the bottom of the stack; it also supplies cell-balancing current for that cell and returns balancing current for the third cell. |
| 4 | VC1 | input | Voltage-sense input for the first cell from the bottom of the stack; it also supplies cell-balancing current for that cell and returns balancing current for the second cell. |
| 5 | VC0 | input | Voltage-sense input for the negative terminal of the bottom cell; it returns balancing current for the first cell. |
| 6 | SRP | input | Analog input to the internal coulomb counter, connected to the top of the sense resistor; charge current produces a positive voltage on SRP relative to SRN. |
| 7 | SRN | input | Analog input to the internal coulomb counter, connected to the bottom of the sense resistor; charge current produces a positive voltage on SRP relative to SRN. |
| 8 | TS | bidirectional | Thermistor input or general-purpose ADC input, and a wake-up source from the SHUTDOWN state. |
| 9 | DSG | output | Gate drive output for the NMOS discharge FET. |
| 10 | CHG | output | Gate drive output for the NMOS charge FET. |
| 11 | VSS | power_in | Device ground. |
| 12 | SCL | bidirectional | I2C serial communication bus clock (open-drain), supporting up to 400 kHz. |
| 13 | SDA | bidirectional | I2C serial communication bus data (open-drain). |
| 14 | ALERT | output | Digital interrupt output (open-drain); pulled low by the device when an enabled alert flag is set. |
| 15 | REGOUT | output | Output of the LDO, programmable to 1.8 V, 2.5 V, 3.0 V, 3.3 V or 5.0 V. |
| 16 | REGSRC | input | Input to the REGOUT LDO; also serves as the power supply for the CHG and DSG FET drivers. |
| 17 | BAT | power_in | Main power input pin for the device. |
| 18 | VC7 | input | Voltage-sense input for the seventh cell from the bottom of the stack; it also supplies balancing current for that cell and serves as the top-of-stack measurement point. |
| 19 | VC6 | input | Voltage-sense input for the sixth cell from the bottom of the stack; it also supplies balancing current for that cell and returns balancing current for the seventh cell. |
| 20 | VC5 | input | Voltage-sense input for the fifth cell from the bottom of the stack; it also supplies balancing current for that cell and returns balancing current for the sixth cell. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
