**Texas Instruments** · Supervisor and Reset ICs · VQFN-16-EP(3x3)

INA230AIRGTR from Texas Instruments, in a VQFN-16-EP(3x3). 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 | A1 | input | I2C address select pin 1. Tie to GND, SCL, SDA, or VS to select one of 16 device addresses (see Table 8-2). |
| 2 | A0 | input | I2C address select pin 0. Tie to GND, SCL, SDA, or VS to select one of 16 device addresses (see Table 8-2). |
| 3 | ALERT | output | Multi-functional alert output, open-drain. Requires an external pull-up to the logic supply; asserts low on programmable threshold or conversion-ready events. |
| 4 | SDA | bidirectional | I2C serial data line, open-drain input/output. Requires an external pull-up to the logic supply. |
| 5 | SCL | input | I2C serial clock input, open-drain. Requires an external pull-up to the logic supply; absolute max VS+0.3 V. |
| 6 | NC | unconnected | No internal connection. May be left floating or tied to ground for board layout convenience. |
| 7 | NC | unconnected | No internal connection. |
| 8 | NC | unconnected | No internal connection. |
| 9 | VS | power_in | Analog power supply input, 2.7 V to 5.5 V. Decouple with a 0.1 µF capacitor to GND close to the pin. |
| 10 | GND | power_in | Ground reference for the device analog supply and digital I/O. |
| 11 | VBUS | input | Bus voltage input. Measures 0 V to 36 V common-mode bus voltage with 1.25 mV LSB; 830 kΩ input impedance. |
| 12 | IN- | input | Negative differential shunt voltage input. For high-side applications connect to the load side of the sense resistor; for low-side, connect to the ground side. |
| 13 | IN+ | input | Positive differential shunt voltage input. For high-side applications connect to the bus voltage side of the sense resistor; for low-side, connect to the load side. Shunt input range ±81.92 mV, 2.5 µV LSB. |
| 14 | NC | unconnected | No internal connection. |
| 15 | NC | unconnected | No internal connection. |
| 16 | NC | unconnected | No internal connection. |
