Working Principle of MCP130-485DI/TO

MCP130-485DI/TO operates by using a voltage supervisor circuit to monitor the system power supply voltage. It measures the power supply voltage and compares it to the preset voltage threshold. If the voltage drops below the preset threshold, MCP130-485DI/TO outputs a reset signal internally to reset the system.The device also has an internal watchdog timer (WDT) that is used to detect whether or not the program is running normally. If a pre-defined time period has elapsed without an adequate reset signal being received, the device will output a signal to reset the system.The device also has an integrated voltage protection feature that can determine when the input voltage is too low or too high. When the input voltage exceeds the highest or lowest operating voltage, the device prevents the voltage from reaching sensitive system components. In addition, the device has an adjustable reset latch time, which allows users to configure the reset signal duration according to their system requirements. The user can also adjust the delay time between the voltage supervisor signal and the reset signal, so that the reset signal can be sent earlier or delayed to the system.

Conclusion

MCP130-485DI/TO is a high-accuracy micropower supervisor family with many built-in features and advantages. It is designed to monitor the system power supply voltage and output a reset signal when the voltage drops below the preset threshold. It also features a wide voltage range, high accuracy, low power consumption, adjustable window watchdogs for system resetting, programmable reset levels and limits, integrated voltage protection, adjustable reset latch time and an integrated toggle filter to prevent false reset pulses. It is a great solution for low power and low voltage applications.
