BQ29413PWR 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, with recommended input range 0 V to 25 V and absolute maximum of -0.3 V to 28 V. |
| 2 | VC2 | input | Sense voltage input for the second most positive cell, with recommended input range 0 V to 25 V and absolute maximum of -0.3 V to 28 V. |
| 3 | VC3 | input | Sense voltage input for the third most positive cell, with recommended input range 0 V to 25 V and absolute maximum of -0.3 V to 28 V. |
| 4 | GND | power_in | Ground pin; all device voltages are referenced to this pin, and the VC4 to GND difference is limited to 0 V to 5 V in recommended operation. |
| 5 | VC4 | input | Sense voltage input for the least positive cell, with recommended input range 0 V to 25 V and VC4 to GND limited to 0 V to 5 V. |
| 6 | CD | passive | External capacitor connection that sets the overvoltage detection delay, where td = 1.2 V x C / 0.18 µA with a recommended capacitance of 0.22 µF, and which is clamped to GND to discharge when cell voltages fall below V(PROTECT). |
| 7 | VDD | power_in | Power supply input with recommended range 4 V to 25 V and absolute maximum of 28 V, typically filtered with RVD of 0 to 1 kΩ and CVD of 0.1 µF. |
| 8 | OUT | output | Overvoltage protection output that goes high when the CD pin reaches 1.2 V and returns low after all cells fall below V(PROTECT) − Vhys, with absolute maximum of -0.3 V to 28 V. |
