**Texas Instruments** · Supervisor And Reset ICs · VSSOP-10-0.5mm

INA226AQDGSRQ1 from Texas Instruments, in a VSSOP-10-0.5mm. 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 | A1 | input | Address pin 1, connect to GND, SCL, SDA, or VS to set I2C slave address per Table 6-2. |
| 2 | A0 | input | Address pin 0, connect to GND, SCL, SDA, or VS to set I2C slave address per Table 6-2. |
| 3 | Alert | tri_state | Multi-function alert open-drain output for programmed alarm conditions. |
| 4 | SDA | bidirectional | I2C serial bus data line, open-drain input/output, requires external pull-up resistor. |
| 5 | SCL | input | I2C serial bus clock line, open-drain input, requires external pull-up resistor. |
| 6 | VS | power_in | Power supply input, 2.7V to 5.5V. |
| 7 | GND | power_in | Ground reference. |
| 8 | VBUS | power_in | Bus voltage input for supply voltage measurement, 0V to 36V. |
| 9 | IN- | input | Negative input for shunt voltage measurement, connect to load side of shunt resistor. |
| 10 | IN+ | input | Positive input for shunt voltage measurement, connect to power side of shunt resistor. |
