BQ2002SNTR

Texas Instruments · Battery Management · SOIC-8

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.
