# BQ24024DRCR

**Texas Instruments** · Battery Management · WSON-10-EP(3x3)

BQ24024DRCR from Texas Instruments, in a WSON-10-EP(3x3). 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 | AC | input | AC charge input voltage |
| 2 | USB | input | USB charge input voltage |
| 3 | STAT1 | output | Charge status output 1, open-drain configuration |
| 4 | STAT2 | output | Charge status output 2, open-drain configuration |
| 5 | VSS | power_in | Ground input; internal electrical connection to exposed thermal pad which must be connected to the same potential as VSS on PCB |
| 6 | ISET1 | input | Charge current set point for AC input and precharge and taper set point for both AC and USB |
| 7 | ISET2 | input | Charge current set point for USB port: high=500 mA, low=100 mA, high-impedance=disable USB charge |
| 8 | TTE | input | Timer and termination enable input, active low |
| 9 | TS | input | Temperature sense input for battery temperature monitoring during charge |
| 10 | OUT | output | Charge current output to battery pack, rated for up to 1.0 A DC |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
