INA229AIDGST 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 | CS | input | SPI chip select input, active low; the SPI transaction runs from the CS falling edge to the CS rising edge, and the MISO output is high-impedance while CS is high. |
| 2 | MOSI | input | SPI digital data input (SPI slave input / master output), sampled on the falling edge of SCLK. |
| 3 | ALERT | output | Open-drain alert output, active low by default (polarity configurable via APOL); it must be pulled up through a resistor. |
| 4 | MISO | tri_state | SPI digital data output (slave output / master input), push-pull, shifted out on the rising edge of SCLK and high-impedance when CS is high. |
| 5 | SCLK | input | SPI clock input, rated up to 10 MHz SPI bit frequency. |
| 6 | VS | power_in | Device power supply, 2.7 V to 5.5 V (recommended operating range). |
| 7 | GND | power_in | Ground reference; the datasheet notes the device should not be operated powered with the GND pin disconnected. |
| 8 | VBUS | power_in | Bus voltage analog input, measured referenced to GND over 0 V to 85 V (absolute maximum -0.3 V to 85 V). |
| 9 | IN- | input | Negative device input for the shunt sense resistor; connect to the load side of the sense resistor in high-side applications and to the ground side in low-side applications (common-mode range -0.3 V to 85 V). |
| 10 | IN+ | input | Positive device input for the shunt sense resistor; connect to the supply side in high-side applications and to the load side in low-side applications (common-mode range -0.3 V to 85 V). |
