CJMCU-219 INA219 I2C Bi-Directional DC Current Power Sensor Arus Daya

MCU-219 INA219 i2c Interface Zero Drift Bidirectional Current/Power Monitoring Sensor Module
The MCU-219 Module Is a Zero-Drift, Bidirectional Current/Power Monitoring Integrated Circuit (Ic) With An i2c Interface That Further Strengthens Ti's Energy-Efficient Electronics Portfolio. The In-Industry Degree And Small Size Of The INA219 Not Only Monitors The Voltage Drop On The Shunt Resistor, Senses The Shunt Supply Voltage, But Also Calculates The Power Supply. Available In An Sot23 Package, The Device Provides a Small, Low-Cost Solution For Digital Current Sensing For Servers, Notebook Computers, Power Supplies, Battery Management, And Automotive And Telecom Equipment.

The INA219 Achieves 1% Error Accuracy Over a Temperature Range Of -40c To +85c With An Offset Of 100 Uv. The High Accuracy Combined With The Benefits Of 12-Bit Resolution Helps Customers Minimize Voltage Drops On Shunt Resistors, Minimizing Power Loss And Power Dissipation And Saving Board-Level Space. The Device Can Sense Bus Voltages From 0 v To +26 v.

Other Important Features Of The INA219 Include:

Programmable Calibration Registers Read Current Directly In Amperes And Power In Watts.

Up To 128 Samples Can Be Averaged For Filtering In Noisy Environments.

The i2c Interface Features a Timeout Setting That Not Only Avoids Bus Lockout, But Also Provides High-Speed Mode For Communication Requirements Up To 3.4 Mhz.

All Features Of The INA219 Support Software Programmability.

Operates From a Single Supply And Operates From +3.0 To +5.5v.
