BQ25070DQCT from Texas Instruments, in a WSON-10-EP(2x3). 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 connected to the external DC supply (AC adapter or USB port), which must be bypassed to GND with at least a 0.1 µF ceramic capacitor; recommended operating range is 3.75 V to 28 V with 10.5 V input over-voltage protection (absolute maximum 30 V). |
| 2 | IMON | output | Current monitoring output where a 1 kΩ resistor from IMON to GND sets a voltage from 0 V to 1 V corresponding to an input current of 0 A to 1 A. |
| 3 | GND | power_in | Ground terminal that must be connected to the thermal pad and the circuit ground plane. |
| 4 | LDO | power_out | LDO output regulated to 4.9 V that drives up to 50 mA, bypassed to GND with a 0.1 µF ceramic capacitor, and enabled when VUVLO < VIN < VOVP. |
| 5 | TS | input | Battery pack NTC monitoring input that connects to the center tap of a resistor divider from LDO to GND with the NTC in parallel with the bottom resistor to set the charge temperature window. |
| 6 | BAT | power_out | Battery connection output and sense input that must be connected to the battery and bypassed to GND with a 1 µF ceramic capacitor. |
| 7 | CTRL | input | Single-input interface that is driven with pulses to enable/disable the device, enable/disable VIN-DPM, and select the input current limit. |
| 8 | CHG | output | Open-drain charge status output that is pulled low while charging and goes high impedance when the battery is fully charged, with ICHG required to stay below 5 mA. |
| 9 | GND | power_in | Ground terminal that must be connected to the thermal pad and the circuit ground plane. |
| 10 | OUT | power_out | System output connection that must be tied to BAT and bypassed to GND with a 1 µF ceramic capacitor. |
| 11 | PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
