BQ29410PWR 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 a recommended input voltage range of 0 V to 25 V and an absolute maximum of 28 V. |
| 2 | VC2 | input | Sense voltage input for the second most positive cell, with a recommended input voltage range of 0 V to 25 V and an absolute maximum of 28 V. |
| 3 | VC3 | input | Sense voltage input for the third most positive cell, with a recommended input voltage range of 0 V to 25 V and an absolute maximum of 28 V. |
| 4 | GND | power_in | Ground pin, which is the reference for all device voltages except the cell-to-cell differential voltages. |
| 5 | VC4 | input | Sense voltage input for the least positive cell, with a recommended input voltage range of 0 V to 25 V and an absolute maximum of 28 V. |
| 6 | CD | passive | External capacitor connection that sets the overvoltage detection delay, where td = 1.2 V × C(DELAY) / I(CD) with I(CD) = 0.18 µA, and the recommended delay capacitance is 0.22 µF; the absolute maximum voltage is 28 V. |
| 7 | VDD | power_in | Power supply input, with a recommended supply range of 4 V to 25 V and an absolute maximum of 28 V. |
| 8 | OUT | output | Overvoltage protection output that goes from low to high once the CD pin reaches 1.2 V to activate the external NCH FET that blows the fuse, with an absolute maximum voltage of 28 V. |
