**Texas Instruments** · Battery Management · SOIC-8

BQ2002ESNTR from Texas Instruments, in a SOIC-8. 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 | TM | input | Three-level input that controls the fast charge safety timer, voltage termination mode, top-off, pulse-trickle, and voltage hold-off time. |
| 2 | LED | tri_state | Open-drain output that indicates the charging status. |
| 3 | BAT | input | Battery voltage sense input created via high-impedance resistor divider network between the positive and negative battery terminals. |
| 4 | VSS | power_in | System ground. |
| 5 | CC | tri_state | Open-drain output for charging current control; high-Z enables charging, low inhibits charging; modulated for top-off and pulse trickle. |
| 6 | INH | input | Charge inhibit input; when high, suspends fast charge in progress; when returned low, resumes operation from suspension point. |
| 7 | VCC | power_in | Supply voltage input, 5.0V ±20%. |
| 8 | TS | input | Temperature sense input for external battery temperature monitoring thermistor. |
