PMIC (Power Management Integrated Circuit) is an integrated circuit of high-density integrated circuit technology to develop power management. TL431BCDMR2G is such a low-power, low voltage voltage reference product developed by Texas Instruments. This device provides a reference voltage of 2.5 V for many applications, as well as a current output of 30mA.

The applications of TL431BCDMR2G include all types of power supply, battery charger, system startup, and other charging systems. Low voltage systems such as hand-held electronic devices, notebook computers, cellular phones, and PDA’s have all benefited from the use of the TL431BCDMR2G. It also has uses in power line communication, over-voltage and over-current protection, operational amplifier negative resistance gain circuit and temperature measurement.

TL431BCDMR2G works by comparing an externally applied voltage to a reference voltage of 2.5 V. This comparison controls the voltage output of the part. The output voltage can range between Vref and ground, and can be adjusted with a variable resistor. Also, the device can become a current regulator when a resistor is connected between the output pin and ground, allowing current to flow and set the current limiting circuit.

A temperature phase compensation circuit is present in the device, to keep the output voltage stable across temperature range and maintain the circuit accuracy. The TL431BCDMR2G also features a built-in reverse current protection to prevent the output from overloading, and can withstand up to a voltage of 30V. The high open-loop gain ensures accuracy for the application, and makes it a great choice for applications where precision is needed.

The TL431BCDMR2G is a convenient voltage reference device with many practical applications, and can be used in numerous types of power supply and battery charging systems. It provides designers with a dependable and cost-effective solution, making it the perfect choice to use in a wide range of applications.
