The INA3221 is a three-channel, high-side current and bus voltage monitor with an I2C- and SMBUScompatible interface. The INA3221 monitors both shunt voltage drops and bus supply voltages, in addition to having programmable conversion times and averaging modes for these signals. The INA3221 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.
The INA3221 senses current on buses that can vary from 0 V to 26 V. The device is powered from a single 2.7-V to 5.5-V supply, and draws 350 uA (typ)of supply current. The INA3221 is specified over the operating temperature range of –40°C to +125°C.
The I2C- and SMBUS-compatible interface features four programmable addresses.1. Triple-Channel with different bus voltage.
2. 0.1 ohm 1% 2W current sense resistor.
3. Up to +26V target voltage, with ±8mV resolution.
4. Up to ±1.638A current measurement, with ±0.4mA resolution.
5. Dimension: 38*32 mm.
6. PCB (no header or terminal block): 4.4g.
7. This board/chip uses I2C 7-bit addresses 0x40, 0x41, 0x44, 0x45, selectable with jumpers.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
