INA219BIDCNT Description

Short technical summary and product information.

The Texas Instruments INA219BIDCNT is a versatile current shunt and power monitor designed for efficient power management in various applications. This IC features an I2C or SMBUS-compatible interface, allowing for seamless integration into digital systems. It monitors both shunt voltage drop and bus supply voltage, offering programmable conversion times and filtering for optimized performance.

 

The INA219BIDCNT boasts a wide bus voltage sensing range of 0 to 26 V and operates on a single 3 to 5.5 V supply. Its high accuracy of ±0.5% over temperature (for the B grade) ensures reliable measurements. The device supports 16 programmable addresses, simplifying system design. It is available in a compact SOT-23-8 package, suitable for surface mount applications.

 

This digital power monitor is capable of direct readouts of current in amperes and calculates power in watts through internal multipliers and programmable calibration registers. Its design facilitates precise monitoring of power consumption and efficiency in electronic systems.
