XC6108C35AGR-G Application Field and Working Principle

The XC6108C35AGR-G is a voltage supervisor device belonging to PMIC (Power Management IC) – Supervisors product line and manufactured by X-Celeprint. The XC6108C35AGR-G monitors the voltage level of digital and analog circuits and provides system reset functionality at an adjustable VDD power supply threshold. This product is designed with a hysteresis of 0.25V to ensure clean input signals for normalized reset timing and low reset current for power conservation.

Overview

The XC6108C35AGR-G is suitable for use in digital circuit monitoring and reset, such as system startup reset, wake/sleep reset and critical power supply reset. This device, housed in an SOT-23-5 package, is capable of driving both a CMOS signal and an open-drain active-low signal. It offers a reset pulse control, providing monitored effective reset width control and glitch immunity.

Features

The XC6108C35AGR-G offers the following features:

• Operation Voltage Range: 2.5V ~ 5.5V
• Reset Output: Open-drain active-low signal and CMOS signal
• Hysteresis: 0.25V
• Low Reset Current: 0.1 µA (Typ.)
• Wide Operating Temperature Range: -40 °C to 105 °C
• Small SOT-23-5 Package

Applications

The XC6108C35AGR-G is suitable for various applications including automatic switches, automotive systems, digital cameras, medical devices and home appliances.

Working Principle

The working principle of the XC6108C35AGR-G is relatively simple. It is composed of an internal reference voltage, a comparator and a reset control signal. The internal reference voltage is compared to the voltage signal being monitored. If the monitored voltage drops below the specified threshold, the comparator signal will trigger a reset control signal and bring the monitored voltage back to the desired level.When the reset control signal is triggered, it will cause the reset output (either open-drain active-low signal or CMOS signal) to be enabled, thus providing a reset signal to the monitored system. The duration of the reset signal depends on the external capacitance and the duration of the monitored voltage being below the threshold.The hysteresis of the XC6108C35AGR-G is set to 0.25V to ensure clean input signals (prevent multiple triggers due to bounce) and to limit the current consumption. After the reset control signal triggers successfully, the comparator will keep the reset control signal low until the monitored voltage rises above the trigger voltage + hysteresis voltage.

Conclusion

The XC6108C35AGR-G is an integrated device manufactured by X-Celprint specifically designed for voltage monitoring and reset applications. The built-in hysteresis ensures clean input signals and reduces current consumption. The device offers multiple reset outputs, making it suitable in various applications including automatic switches, automotive systems, digital cameras, medical devices and home appliances.
