MCU-219 INA219 I2C Interface Zero-Drift Bidirectional Current/Power Monitoring Sensor Module

The MCU-219 module is a zero-drift, bi-directional current/power monitoring integrated circuit (IC) with an I2C interface that adds to TI's lineup of energy-efficient electronics.The INA219 offers the industry's best-in-class performance in a small form factor that not only monitors the voltage drop across shunt resistors and senses the shunt supply voltage, but also calculates the power supply. Available in a SOT23 package, the device provides a small, low-cost solution for digital power measurement in servers, laptops, power supplies, battery management, and automotive and telecom equipment.

The INA219 achieves 1% error accuracy over the temperature range of -40C to +85C with a 100 uV offset, and its high accuracy combined with 12-bit resolution enables customers to minimize voltage drop across shunt resistors, thereby minimizing power loss and consumption and saving board space. The device can sense a total line voltage range of 0 V to +26 V. The INA219 is also available in a wide range of colors.

Other important features of the INA219 include:

A programmable calibration register that reads current directly in amps and power in watts.

Up to 128 samples can be averaged for filtering in noisy environments.

The I2C interface has a timeout setting that not only prevents bus lock-up, but also provides a high-speed mode for communications up to 3.4 MHz.

All features of the INA219 are software programmable.

The INA219 operates from a single power supply with a voltage range of +3.0 to +5.5V.
