CJMCU-219 INA219 I2C Interface Bidirectional DC Current/Power Monitoring Sensor Module
The INA219 offers the industry's highest accuracy and smallest size, not only to monitor the pressure on the shunt resistor, to sense the shunt supply voltage, but also to calculate the power supply.
The device is available in a SOT23 package to provide small, low-cost solutions for digital current sensing of servers, laptops, power supplies, battery management, and automotive and telecom equipment.
The INA219 achieves a maximum error accuracy of 1% over the -40 ° C to + 85 ° C temperature range with a maximum offset of 100 uV.
The high precision of the product combines the advantages of 12-bit resolution to help customers minimize the pressure on the shunt resistor, thus minimizing power loss and power consumption and saving board space.
The I2C interface has a timeout setting that not only prevents bus lockout, but also provides high-speed mode for up to 3.4 MHz communication requirements.
