BQ24400DR 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 | SNS | input | Current-sense input that senses battery current from the voltage developed across an external sense resistor connected in series with the battery pack. |
| 2 | LED | output | Open-drain charge-status output that turns an external LED on, off, or flashing through a series resistor. |
| 3 | BAT | input | Battery-voltage sense input, generated by a simple resistive divider across the battery terminals. |
| 4 | VSS | power_in | System ground, to be connected to the battery's negative terminal. |
| 5 | RC | input | Timer-program input where a capacitor from VCC and a resistor to ground set the maximum fast-charge time, top-off time, hold-off period, trickle-charge rate, and top-off enable. |
| 6 | TS | input | Temperature-sense input for an external divider with a negative-temperature-coefficient thermistor that sets the lower and upper temperature thresholds. |
| 7 | VCC | power_in | Supply-voltage input; the datasheet recommends 10 µF plus 0.1 µF to 0.22 µF of decoupling capacitance near the pin. |
| 8 | MOD | output | Push-pull charging-current control output that switches high to enable charging current and low to inhibit it. |
