BQ24050DSQT

Texas Instruments · Battery Management · WSON-10-EP(2x2)

BQ24050DSQT from Texas Instruments, in a WSON-10-EP(2x2). 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 IN power_in Input power supply (3.5 V to 28 V) with 1 μF to 10 μF bypass capacitor to VSS for AC adapter or USB port connection
2 ISET input Fast-charge current programming resistor to VSS (range 52.3 kΩ for 10 mA to 540 Ω for 1 A)
3 VSS power_in Ground terminal
4 PRETERM input Precharge and termination threshold programming resistor to VSS (range 1 kΩ to 10 kΩ for 5% to 50% termination threshold)
5 D+ input USB port D+ input connection for automatic adapter and USB source detection
6 D- input USB port D- input connection for automatic adapter and USB source detection
7 ISET2 input Three-state input current limit control (High = 500 mA max, Low = ISET resistor value, Float = 100 mA max)
8 CHG tri_state Charging status open-drain output, active low (FET on) during first charge cycle only, high-impedance when charging complete or disabled
9 TS input Temperature sense input for 10k NTC thermistor (BQ24050 variant) for JEITA temperature monitoring, Termination and Timer Disable Mode when floating or pulled high, or chip disable when pulled low
10 OUT power_out Battery output connection with 1 μF to 10 μF bypass capacitor to VSS, maximum 1.25 A continuous, for battery charging and system load
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
