BQ29410DCT3R from Texas Instruments, in a MSOP-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 | OUT | output | Overvoltage protection output that goes high when the CD pin reaches 1.2 V and returns low after all cells fall to V(PROTECT) minus Vhys; absolute maximum output voltage is 28 V. |
| 2 | VDD | power_in | Power supply input, recommended 4 V to 25 V with a 0.1 µF filter capacitor and up to 1 kΩ filter resistor, absolute maximum 28 V. |
| 3 | CD | passive | Connection for the external delay capacitor (0.22 µF typical in the datasheet example) that sets the overvoltage detection delay; the pin reaches 1.2 V to activate OUT, and absolute maximum voltage is 28 V. |
| 4 | VC4 | input | Sense voltage input for the least positive cell; recommended input range is 0 V to 25 V, and the VC4 to GND difference is limited to 0 V to 5 V. |
| 5 | GND | power_in | Ground reference pin for the device; all voltages are referenced to this pin except the cell-to-cell differential voltages. |
| 6 | VC3 | input | Sense voltage input for the third most positive cell; recommended input range is 0 V to 25 V, and the VC3 to VC4 difference is limited to 0 V to 5 V. |
| 7 | VC2 | input | Sense voltage input for the second most positive cell; recommended input range is 0 V to 25 V, and the VC2 to VC3 difference is limited to 0 V to 5 V. |
| 8 | VC1 | input | Sense voltage input for the most positive cell; recommended input range is 0 V to 25 V, and the VC1 to VC2 difference is limited to 0 V to 5 V. |
