INA230AIRGTR

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.
