STC3115AIQT from STMicroelectronics, in a DFN-10(2x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ALM | tri_state | Alarm signal output, open drain, requires external pull-up resistor. |
| 2 | SDA | tri_state | I2C serial data line, open drain bidirectional, supports data transfers up to 400 kbit/s. |
| 3 | SCL | tri_state | I2C serial clock line, open drain, supports clock frequency 0 to 400 kHz. |
| 4 | NC | unconnected | Not connected. |
| 5 | GND | power_in | Analog and digital ground. |
| 6 | CG | input | Current sensing input with input voltage range -40 mV to +40 mV and input current 500 nA. |
| 7 | RSTIO | tri_state | Reset sense input and reset control output, open drain, used for platform synchronization. |
| 8 | BATD/CD | bidirectional | Battery detection analog input with 1.61 V threshold and battery charge inhibit active-high output driving to VCC level. |
| 9 | VCC | power_in | Power supply input, operating voltage range 2.7 V to 4.5 V. |
| 10 | VIN | power_in | Battery voltage sensing input, voltage range 0 V to 4.5 V with 2.20 mV LSB resolution. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
