BQ2002SNTR 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, top-off, pulse-trickle and voltage hold-off time, with the mid level set by a resistor divider to VCC/2 ±0.5V. |
| 2 | LED | output | Open-drain charging status output that goes low during fast charge and is high-Z otherwise, with VOL of at most 0.8V at IOL = 10mA. |
| 3 | BAT | input | Battery voltage sense input fed by a high-impedance divider (end-to-end impedance at least 200kΩ and less than 1MΩ); fast charge is valid only while VBAT is below the maximum cell voltage VMCV = 2V ±5%. |
| 4 | VSS | power_in | System ground reference for all pin voltages. |
| 5 | CC | output | Open-drain charge control output where high-Z enables charging current and low inhibits it, sinking at least 10mA at VOL = VSS + 0.8V. |
| 6 | INH | input | Charge inhibit input where high suspends fast charge and top-off and the charge resumes from the suspended point when returned low, with input low at most 0.1V. |
| 7 | VCC | power_in | Supply input rated 5.0V ±20%, with a recommended DC operating range of 4.0V to 6.0V. |
| 8 | TS | input | Temperature sense input from a ground-referenced negative-temperature-coefficient thermistor network between VCC and VSS, where fast charge is inhibited when VTS is at or below VTCO = 0.5 × VCC ±5% and VTS below 0.5V is prohibited. |
