BQ29410PWR

Texas Instruments · Battery Management · TSSOP-8

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.
