TEXAS INSTRUMENTS · Global Sourcing Parts · VQFN-20-EP(3.5x3.5)

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).

CAD (KiCad official)

  • Symbol: BQ76907RGRR
  • Footprint: Package_DFN_QFN:QFN-20-1EP_3.5x3.5mm_P0.5mm_EP2x2mm
  • 3D model: VQFN-20-EP(3.5x3.5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: bq76907rgrr-etched.step / bq76907rgrr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bq76907rgrr.step / bq76907rgrr.glb are the bare package body.
