BQ29419PWR from Texas Instruments, in a TSSOP-8. 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 | VC1 | input | Sense voltage input for the most positive cell; recommended VC1 input range is 0 V to 25 V, with an absolute maximum of -0.3 V to 28 V. |
| 2 | VC2 | input | Sense voltage input for the second most positive cell; recommended VC2 input range is 0 V to 25 V, with an absolute maximum of -0.3 V to 28 V. |
| 3 | VC3 | input | Sense voltage input for the third most positive cell; recommended VC3 input range is 0 V to 25 V, with an absolute maximum of -0.3 V to 28 V. |
| 4 | GND | power_in | Ground pin; all device voltages are specified with respect to this ground, except the cell-to-cell differential voltages. |
| 5 | VC4 | input | Sense voltage input for the least positive cell; the VC4-to-GND input is limited to 0 V to 5 V in recommended operation, with an absolute maximum of -0.3 V to 28 V. |
| 6 | CD | passive | External capacitor connection that sets the programmable overvoltage delay; the CD pin must reach 1.2 V to activate OUT, has an absolute maximum of -0.3 V to 28 V, and is clamped to GND when no overvoltage is present. |
| 7 | VDD | power_in | Power supply input with a recommended range of 4 V to 25 V and an absolute maximum of -0.3 V to 28 V. |
| 8 | OUT | output | Overvoltage protection output that transitions high when the CD pin reaches 1.2 V to activate the external NCH FET that blows the battery fuse; absolute maximum is -0.3 V to 28 V. |
