XC61HC1812MR-G

PMIC - Supervisors

The XC61HC1812MR-G is a voltage supervisor specifically designed for monitoring low voltage and low current supply lines in electronic systems. It is used in electronic products such as notebook and desktop computers, gaming consoles, DVD players, digital cameras, and other electronic products. The device has a wide operating voltage range (2.2 to 12V) and can detect a minimum voltage difference between its two independent voltage monitoring pins. The XC61HC1812MR-G is a highly integrated microcontroller-based device that ensures system stability by continually monitoring supply and reset voltages and triggering a reset or interrupt signal when any deviations that exceed the preset levels occur. In addition, the device features an on-chip watchdog timer and an integrated energy-saving sleep mode, allowing it to function with the minimum power consumption and improving the overall system efficiency.

Application Field

The XC61HC1812MR-G is mainly used in applications that require precise voltage monitoring and low power consumption. The device is especially suited for applications in the consumer electronics, communications, microcontroller systems, or industrial embedded control systems. It can be used to monitor, protect, and reset the systems. For example, it can be used as a supply voltage supervisor in an embedded system to continually monitor the supply voltage and detect any changes, and then trigger a reset or interrupt signal when the level reaches the preset limit. It is also useful in applications where power consumption needs to be kept to a minimum, such as portable and battery-operated devices.

Working Principle

The XC61HC1812MR-G works by monitoring and comparing the voltage level between two independent voltage monitoring pins, designated as Vdd and Vss. It also includes an adjustable reference voltage for user-defined voltage levels and an adjustable delay timer for timing out a reset or interrupt signal if the monitored voltage level remains outside the pre-set range. When a voltage difference between the two pins occurs, the device will emit an interrupt ALERT signal or a system reset signal, depending on the user’s configuration.

The device also includes a watchdog timer that can be used to detect and prevent system lock-ups. When enabled, the watchdog timer will generate a reset pulse whenever the operating is unable to respond to the timer signals. Moreover, the device features an energy-saving sleep mode that can be used to reduce the power consumption of idle or standby systems.

In summary, the XC61HC1812MR-G is a highly integrated voltage supervisor that can be used to monitor, protect, and reset the systems in various applications. It is designed to meet the demanding requirements of modern low-power electronics while providing stable and reliable system performance.
