PMIC - Voltage Reference is a type of integrated circuit used to provide a certain reference voltage level to the system, regardless of any changes that may occur in supply or temperature. This stability is achieved by the internal protection circuit of the device. REF6125IDGKT is a typical example among different voltage reference products. It is developed by Texas Instruments, and it is ideal for digital power systems. This application brief will discuss the application field and working principle of REF6125IDGKT.

High accurate and stable DC reference voltage is always required in modern electronic systems, such as power management, automotive and industrial equipment, where accurate voltage values can ensure the accuracy of different measurements and provide protection for the system components. REF6125IDGKT devices are optimized for digital power systems, which provide users with robust operation in the operating environment ranging from –40°C up to 125°C, and a cost-effective solution to meet different demanding applications. The high performance of the device is further proven by its 2.5V output rating accuracy of 1000ppm/°C, and 100ppm/V voltage reference line regulation.

REF6125IDGKT is a low-power voltage reference device which includes a 1.2V voltage reference, a 2.5V voltage reference and a 2.5V voltage reference buffer. The 1.2V and 2.5V voltage reference are corresponding to the two input pinsref1 and ref2, each serves as an individual reference voltage output pin. And the 2.5V voltage reference buffer is connected to the ref2 pin. As for the operating power, REF6125IDGKT accepts input voltage of 1.35V to 5.5V though its VDD pin, and has a very low quiescent current of 50uA for the 1.2V and 2.5V reference, and 45uA for the 2.5V reference buffer.

In addition to supplying the reference voltage values, REF6125IDGKT also provides overvoltage and alarm protection. It includes an in-built resistor divider and a comparator, where the comparator can selectively remove one or both of the reference outputs to trigger an output alarm indicator, depending on the operating input voltage or other system conditions. This OVP can help to protect the system from damage when any fault occurs and also provide users with a simple and quick way to detect errors thus improve system reliability significantly.

The stable output of REF6125IDGKT also allows it to work effectively under noisy conditions, because the internal safeguard circuit provides a good noise suppression capability to protect the output voltage from the influence of external electromagnetic noises. This feature makes it suitable for applications such as had-held devices, PDAs etc., which are more prone to electromagnetic interference.

Due to its wide range of features, REF6125IDGKT is suitable for many digital power systems requiring accurate, stable and low-noise reference voltage. Its wide range of temperature performance also adds to its application field. In summary, REF6125IDGKT is a great choice among the different voltage reference products, and it can be used to provide reliable and accurate voltage reference within different system applications.
