BQ2002GSN from Texas Instruments, in a SOIC-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 | TM | input | Three-level timer mode input that selects the fast-charge safety timer, voltage termination mode (PVD or -ΔV), top-off, pulse-trickle rate and hold-off time; mid level is VCC/2 ± 0.5V. |
| 2 | LED | output | Open-drain charge status output that goes low during fast charge and is high-Z in all other conditions, sinking 10mA at VOL ≤ 0.8V. |
| 3 | BAT | input | Battery voltage sense input fed from a high-impedance resistor divider (RB1/RB2 = N-1, 200kΩ to 1MΩ end-to-end) representing a single-cell potential, valid from 0 to VCC. |
| 4 | VSS | power_in | System ground. |
| 5 | TS | input | Temperature sense input for an external NTC thermistor network, where VTS below 0.5V is prohibited, fast charge terminates below 0.5VCC and start is inhibited below 0.6VCC. |
| 6 | VCC | power_in | Supply voltage input of 5.0V ±20% (4.0V to 6.0V recommended, 7.0V absolute maximum). |
| 7 | INH | input | Charge inhibit input that suspends fast charge, top-off and the charge timer when high and resumes when returned low; also used for synchronized voltage sampling pulses of 100ns to 3.5ms. |
| 8 | CC | output | Open-drain charge control output where high-Z enables charging current and low inhibits it, modulated for top-off and pulse trickle, sinking 10mA at VOL ≤ 0.8V. |
