Texas Instruments · Battery Management · TSSOP-8

BQ29419PWR 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; recommended VC1 input range is 0 V to 25 V, with an absolute maximum of -0.3 V to 28 V.
2 VC2 input Sense voltage input for the second most positive cell; recommended VC2 input range is 0 V to 25 V, with an absolute maximum of -0.3 V to 28 V.
3 VC3 input Sense voltage input for the third most positive cell; recommended VC3 input range is 0 V to 25 V, with an absolute maximum of -0.3 V to 28 V.
4 GND power_in Ground pin; all device voltages are specified with respect to this ground, except the cell-to-cell differential voltages.
5 VC4 input Sense voltage input for the least positive cell; the VC4-to-GND input is limited to 0 V to 5 V in recommended operation, with an absolute maximum of -0.3 V to 28 V.
6 CD passive External capacitor connection that sets the programmable overvoltage delay; the CD pin must reach 1.2 V to activate OUT, has an absolute maximum of -0.3 V to 28 V, and is clamped to GND when no overvoltage is present.
7 VDD power_in Power supply input with a recommended range of 4 V to 25 V and an absolute maximum of -0.3 V to 28 V.
8 OUT output Overvoltage protection output that transitions high when the CD pin reaches 1.2 V to activate the external NCH FET that blows the battery fuse; absolute maximum is -0.3 V to 28 V.
