BQ2002FSNTR

Texas Instruments · Battery Management · SOIC-8

BQ2002FSNTR 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 hold-off time; mid level is VCC/2 ± 0.5V set by a resistor divider.
2 LED output Open-drain charging status output that goes low during fast charge and is high-Z otherwise, with VOL max 0.8V at IOL = 10mA.
3 BAT input Battery voltage sense input from a high-impedance resistor divider (200kΩ to 1MΩ end-to-end) representing a single-cell potential, valid 0 to VCC.
4 VSS power_in System ground.
5 TS input Temperature sense input for an external NTC thermistor network between VCC and VSS; VTS below 0.5V is prohibited and VTS at or below 0.5*VCC terminates/inhibits fast charge.
6 VCC power_in Supply voltage input of 5.0V ±20% (4.0V to 6.0V recommended operating range).
7 INH input Charge inhibit input that suspends fast charge, top-off and the charge timer when high and resumes from the suspended point when returned low.
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, with VOL max 0.8V at IOL = 10mA.
