BQ29410DCT3R

Texas Instruments · Battery Management · MSOP-8

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.
