MCU-219 INA219 I2C interface zero drift two-way current / power monitoring sensor module

Due to the shortage of the chip, you will use a larger chip to mind not to shoot

INA219 I2C interface zero drift bidirectional current / power monitoring sensor module

The CJMCU-219 module is a zero drift with the I2C interface, two-way current / power monitoring integrated circuit (IC), which further strengthened the TI energy-saving electronic product camp.INA219 has the highest accuracy of the industry and the smallest size, which can monitor the voltage drops on the diversion resistor, but also the sensing diversion power supply voltage, but also calculate the power supply.This device is packaged in SOT23, which can provide small and low -cost solutions for server, laptop computer, power supply, battery management, and digital current testing of vehicle and telecommunications devices.

Ina219 can achieve a maximum error accuracy of 1% within the temperature range of -40c to +85C, and the maximum offset is 100 UV.The high precision of this product combines the advantages of 12 -bit resolution, which can help customers reduce the pressure on the diversion resistor as much as possible, thereby minimizing power loss and power consumption, and saving board -level space.The sensing bus voltage range of this device is 0 V to +26 V.

Other important features of INA219 include::

The programmable calibration register can directly read the current in the unit and read the power supply in Watt.
Average of up to 128 sampling is available to achieve filtration in noise environment.
I2C interface has timeout settings, which can not only avoid locking in the bus, but also provide high -speed mode to meet the communication requirements of up to 3.4 MHz.
All features of INA219 support software programming.
With a single power supply, its working voltage is between +3.0 to +5.5V.
