Features:
The INA219 module is a bidirectional current/power monitoring integrated circuit (IC) with an I2C interface, which further strengthens TI’s energy-saving electronic product camp.
INA219 has the industry’s highest accuracy and the smallest size. It can not only monitor the voltage drop across the shunt resistor, sense the shunt supply voltage, but also calculate the power supply. The device is packaged in SOT23 and provides a small, low-cost solution for digital current sensing in servers, laptops, power supplies, battery management, and automotive and telecommunications equipment.
The INA219 achieves a maximum error accuracy of 1% over a temperature range of -40C to + 85C, with a maximum offset of 100 uV. The high accuracy of this product combined with the advantages of 12-bit resolution can help customers minimize the voltage drop across the shunt resistor, thereby minimizing power loss and power consumption, and saving board space. The device can sense bus voltage from 0 V to +26 V.
