The MN13811SL is a PMIC - Supervisors that is used in applications that require power-on reset and power-fail monitoring. It can be used in microprocessor-based systems, such as those found in consumer electronics, automotive systems, industrial controllers, and medical devices. The MN13811SL offers multiple reset functions, including setting trip points for monitoring system voltage, resetting the processor when a fault or power-fail occurs, and providing an output signal for debugging.The main feature of the MN13811SL is its ability to monitor and report power-fail conditions, and trigger a reset signal when it detects an error. The device uses an on-chip voltage regulator and voltage divider to measure the voltages of different power supplies. When the voltage dips below the selected reset threshold, the device will trigger an active Low signal to reset the processor, while simultaneously providing an output signal which can be used for debugging.Apart from monitoring the power-fail condition and resetting the processor, the MN13811SL can also be used to monitor system voltages. It includes a 10-bit analog-to-digital converter (ADC) to accurately measure the voltages of up to four power supplies. The trip points can be configured to trigger a reset at a predetermined voltage, allowing the system to be more efficiently monitored and more resilient to sudden voltage drops.Furthermore, the MN13811SL includes an additional programmable feature - the Watchdog Timer (WDT). The WDT ensures that the processor does not become stuck in an infinite loop and can be used as an external watchdog for monitoring system operation. It can be set to reset the processor if a problem occurs, allowing the system to recover from errors without compromising performance.To summarize, the MN13811SL is a PMIC - Supervisors that can be used in microprocessor-based systems to provide power-fail monitoring, reset functions, and system voltage monitoring. It can also be used to set trip points for resetting the processor when the voltage drops below a certain threshold, as well as to monitor system operation with the built-in WDT. The MN13811SL offers a reliable and robust solution for controlling and monitoring microprocessor-based systems.
