Texas Instruments · Battery Management · WSON-8-EP(2x2)
BQ294705DSGR from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Unregulated IC power input, recommended range 3V to 20V, absolute max 30V; typically filtered with a series resistor and decoupling capacitor to VSS. |
| 2 | V4 | input | Analog sense input for the positive terminal voltage of the fourth (topmost) cell from the bottom of the battery stack, monitored as V4-V3 for overvoltage detection. |
| 3 | V3 | input | Analog sense input for the positive terminal voltage of the third cell from the bottom of the battery stack, monitored as V3-V2 for overvoltage detection. |
| 4 | V2 | input | Analog sense input for the positive terminal voltage of the second cell from the bottom of the battery stack, monitored as V2-V1 for overvoltage detection. |
| 5 | V1 | input | Analog sense input for the positive terminal voltage of the bottommost cell in the battery stack, monitored as V1-VSS for overvoltage detection. |
| 6 | VSS | power_in | Ground reference pin, electrically connected to the IC ground and to the negative terminal of the bottommost cell in the battery pack. |
| 7 | CD | output | Analog output/timing pin for connection of an external capacitor that sets the overvoltage fault delay timer (tCD = K x CCD, K=10 to 20); also includes open/short timeout detection on this pin. |
| 8 | OUT | output | Analog output driver for the overvoltage fault signal; for this active-high CMOS version (BQ294705), OUT is pulled high (toward VDD) when an overvoltage fault is active and driven low (typ. 250-400 mV) when no fault is present. |
| 9 | PowerPAD | power_in | Exposed thermal pad; TI recommends connecting the exposed pad to VSS on the PCB, and it must be soldered to the board for proper thermal and mechanical performance. |
