VRE410JS Application Field and Working Principle

VRE410JS is a voltage reference from Microchip\'s PMIC - Voltage Reference. VRE410JS is a low-power voltage reference device that provides 0.2mA current over its 2V to 10V adjustable range and is typically used to provide a stabilized signal to microcontrollers.

Application Field

One of the most common application fields for the VRE410JS is in microcontrollers, where the voltage reference is used to provide a stabilized signal. In microcontroller applications, the VRE410JS is used to adjust the CPU’s core voltage, provide the microcontroller with a stable voltage level, and providing a mezzanine output voltage level to other integrated circuits on the board.The VRE410JS can also be used in other applications such as battery chargers, motor control systems, and power supply designs. The voltage reference can provide high accuracy and stable reference voltages for a broad range of designs. The device also features a low power consumption of 1.6mW, reducing the overall system power consumption.

Working Principle

VRE410JS is based on a bandgap operation and uses a combination of thin film resistors and NMOS passes to produce a low-power and accurate voltage reference. The reference voltage of VRE410JS is highly accurate and stable. Furthermore, the device is capable of regulating an output voltage that is different from the input voltage. The output voltage is determined by the ratio of the resistive elements that make up the resistive divider. The thin film resistors and NMOS pass transistors connected to the resistive divider form an analog building block that sets the output voltage. When the input voltage is constant, the output voltage will remain stable. In addition to its low power consumption, the VRE410JS features an integrated active buffering, capable of supplying up to 200mA to the load. This increases the versatility of the device and makes it suitable for applications that require high load currents.The VRE410JS also offers a low-power shutdown mode, which reduces the quiescent current consumption to 1nA. This makes the device well suited for applications that require very low power consumption while in standby mode.

Conclusion

The VRE410JS is an excellent solution for applications requiring an adjustable low-power voltage reference. Its low power consumption and high accuracy make it an excellent choice, while its buffering and high load capabilities further increase its versatility. Furthermore, its integrated shutdown mode provides an even lower power consumption, making it a suitable choice for applications where power saving is critical.
