INA228AQDGSRQ1

Texas Instruments · Power Supply Controllers, Monitors · MSOP-10-3mm

INA228AQDGSRQ1 from Texas Instruments, in a MSOP-10-3mm. Symbol, footprint and 3D model are the ones used on Adom board designs (KiCad official libraries). Pin functions are extracted from the manufacturer datasheet with page references.

Pinout

Pin Name Type Function
1 A1 input I²C address pin. Connect to GND, SCL, SDA, or VS. [datasheet p.3]
2 A0 input I²C address pin. Connect to GND, SCL, SDA, or VS. [datasheet p.3]
3 ALERT open_collector Open-drain alert output, default state is active low. [datasheet p.3]
4 SDA bidirectional Open-drain bidirectional I²C data. [datasheet p.3]
5 SCL input I²C clock input. [datasheet p.3]
6 VS power_in Power supply, 2.7 V to 5.5 V. [datasheet p.3]
7 GND power_in Ground. [datasheet p.3]
8 VBUS input Bus voltage input (analog). [datasheet p.3]
9 IN- input Negative input to the device (analog). For high-side applications, connect to the load side of the sense resistor; for low-side applications, connect to the ground side of the sense resistor. [datasheet p.3]
10 IN+ input Positive input to the device (analog). For high-side applications, connect to the power-supply side of the sense resistor; for low-side applications, connect to the load side of the sense resistor. [datasheet p.3]
