INA219AID +BOM

26-V 12-bit I2C output digital power monitor

INA219AID Information

Description

The Texas Instruments INA219AID is a high-accuracy, zero-drift current and power monitor with a bi-directional current sense amplifier. It senses bus voltages from 0 to 26V and reports current, voltage, and power. The device features 16 programmable addresses, filtering options, and calibration registers. It's available in SOT23-8 and SOIC-8 packages. The INA219AID is commonly used in various applications such as power monitoring, battery management, and energy measurement in devices like smart meters, solar panels, and portable electronics. It's also utilized in motor control, robotics, and industrial automation for current sensing and power management. This device provides high accuracy and flexibility, making it suitable for a wide range of applications where precise current and power monitoring is required.

Features

The INA219AID features include:

  • Senses bus voltages from 0 to 26 V
  • Reports current, voltage, and power
  • 16 programmable addresses
  • High accuracy: 0.5% (maximum) over temperature (INA219B)
  • Filtering options
  • Calibration registers
  • Available in SOT23-8 and SOIC-8 packages

Package

The package type of INA219AID is 8-SOIC (0.154", 3.90mm Width).

Pinout

The INA219AID is an 8-pin semiconductor component in SOIC-8 package. The functions of each pin are:

  • V+ (Pin 1): Power-in voltage to the device
  • GND (Pin 2, 3, 5, 6, 7, 8): Ground pins
  • SDA (Pin 4): Serial Data Input/Output pin
  • SDI (Pin 6): Serial Clock Input pin

These pins make up the I²C interface, used for communication with external microcontrollers or other devices. The device uses this interface to monitor and report current, voltage, and power levels.

Manufacturer

The manufacturer of the INA219AID is Texas Instruments (TI), a leading global semiconductor company that designs, manufactures, tests, and sells analog and embedded processing semiconductors. TI's products include microprocessors, memory devices, sensors, amplifiers, and other analog components used in a wide range of applications, including industrial, automotive, medical, consumer electronics, and more.

Applications

The INA219AID is commonly used in power monitoring, battery management, energy measurement in smart meters, solar panels, portable electronics, motor control, robotics, and industrial automation for current sensing and power management.
