BQ24400DR

Texas Instruments · Battery Management · SOIC-8

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.
