Texas Instruments · Battery Management · TSSOP-24

BQ7791500PWR from Texas Instruments, in a TSSOP-24. 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 VDD power_in Supply voltage.
2 AVDD output Analog supply; only connect to a capacitor.
3 VC5 input Cell voltage sense input.
4 VC4 input Cell voltage sense input.
5 VC3 input Cell voltage sense input.
6 VC2 input Cell voltage sense input.
7 VC1 input Cell voltage sense input.
8 VC0 input Cell voltage sense input.
9 VSS power_in Analog ground.
10 SRP input Current sense input connecting to the battery side of the sense resistor.
11 SRN input Current sense input connecting to the pack side of the sense resistor.
12 DSG output DSG FET driver output.
13 CHG output CHG FET driver output.
14 LD input PACK- load removal detection input.
15 LPWR output HIBERNATE mode communication pin; leave floating for single device operation.
16 CBI input Cell balancing input; leave floating to disable or drive low to enable.
17 OCDP input Connect resistor from this pin to VSS to program OCD1/2 fault detection delay.
18 TS input Thermistor measurement input; connect 10-kΩ resistor to VSS if not used.
19 VTB output Thermistor bias output.
20 CCFG input Cell in-series configuration input.
21 CBO output Cell balancing output; leave floating for single device operation.
22 PRES input HIBERNATE mode input; drive high for NORMAL mode or leave floating for HIBERNATE mode.
23 CTRC input CHG and DSG override input for CHG FET driver control.
24 CTRD input CHG and DSG override input for DSG FET driver control.
