Voltage reference is a type of integrated circuit(IC) designed to provide a stable voltage sources or other type of reference. It is a critical tool used in analog and mixed signal designs to ensure that accuracy of regulated output. In this article, we\'ll discuss the application field and working principle of an IC called VRE107M.

Application Of VRE107M

VRE107M is a Lithium-Ion battery voltage reference. It is used to provide a highly stable reference voltage source for battery protection circuitries and other functions. With its precision accuracy of 0.06% and line regulation of 0.002%, this particular IC is capable of continuous monitoring and maintains battery voltage within specified limits. Other features include a small footprint, low power consumption and high reliability.

VRE107M can also be used as an accurate 0.4 V voltage reference for voltage regulation applications. It is an excellent choice for regulating small operating currents such as portable electronics and multicamera applications. The IC\'s 0.4 V reference output is very close to ideal 0.4V, which helps minimize DC offset and eliminate excess heat dissipation due to current flowing through the load.

Working Principle Of VRE107M

The VRE107M consists of two main components: a voltage reference circuit and a temperature-compensated oxide layer. The voltage reference circuit is designed to provide a highly accurate, fixed voltage reference. It typically uses a resistor to measure the voltage level and compare it to the reference voltage that has been programmed into the IC. The oxide layer serves as an electrical insulation between the reference resistance and the body of the IC, preventing any electrolyte leakage and ensuring that the reference resistance is maintained within specified limits.

The circuit is designed to provide a low drop-out (LDO) output of 0.4V. This is done by using an internal voltage-error amplifier that senses the voltage difference between the output (Vout) and the reference voltage (Vref). When the difference between the two is greater than the set-point, the control circuit switches the output to a higher voltage until the difference is equal to the set-point. This allows the IC to maintain a consistent output voltage, even when the input voltage changes.

The VRE107M uses a special temperature-compensated oxide layer to ensure that the output voltage remains stable and accurate over a wide range of temperature. This is done by using a special temperature-sensing diode connected to the reference resistor. As the temperature increases, the temperature-sensing diode produces a positive voltage, which is added to the reference voltage and causes the output voltage to increase. Conversely, a decrease in temperature results in a decrease in output voltage.

Conclusion

The VRE107M is a type of integrated circuit designed to provide a highly stable and accurate voltage reference. It is primarily used in Li-ion battery protection circuits and voltage regulation applications. The IC is capable of providing a precise 0.4V reference output, and its temperature-compensated oxide layer helps ensure stability and accuracy over a wide range of temperatures. Overall, the VRE107M is an excellent choice for applications requiring precise and consistent voltage reference.
