INA236AIDDFR from Texas Instruments, in a TSOT-23-8. 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 | IN+ | input | Current sensing positive input; connect to bus voltage side of sense resistor for high-side applications or load side for low-side applications. |
| 2 | IN- | input | Current sensing negative input; connect to load side of sense resistor for high-side applications or ground side for low-side applications; bus voltage measurements made with respect to this pin. |
| 3 | GND | power_in | Ground connection for both analog and digital circuits. |
| 4 | VS | power_in | Power supply voltage input, operating range 1.7 V to 5.5 V. |
| 5 | SCL | input | I2C serial bus clock line, open-drain input. |
| 6 | SDA | bidirectional | I2C serial bus data line, open-drain input/output. |
| 7 | A0 | input | Digital address pin; connect to GND, SCL, SDA, or VS to configure device I2C address per Table 7-1. |
| 8 | ALERT | output | Multifunctional alert output, open-drain; asserts on overcurrent, undercurrent, overvoltage, undervoltage, or power limit conditions as configured, or on conversion ready notification. |
