Description

CJMCU-219 is a module featuring a zero-drift I2C interface and a bi-directional current/power monitoring and control integrated circuit (IC), which expands the TI energy-saving electrical devices. The INA219 has the greatest precision and smallest size in the industry, and it can monitor the pressure drop on the shunt resistor while detecting the shunt power supply voltage and calculating the power. The device is packaged in SOT23, yet it provides a tiny, low-cost solution for the server, laptop computer, power supply, battery management, and digital electric car and communications equipment measurement needs.

The temperature range of the INA219 is -40 C to + 85 C, with a maximum inaccuracy of 1% accuracy and a maximum offset of 100 uV. The advantage of the product’s high accuracy in combination with 12 resolution is that it can aid clients as much as possible by reducing the pressure drop on the shunt resistor, hence minimizing power loss and power consumption and saving board space. The epic of the 26 bus voltage range is 0 V to +26 V.
