BD4850FVE-TR is a supervisory IC from Rohm with an embedded watchdog timer. As a component of IBM\'s PMIC (Power Management ICs) family, this device is being used in a variety of applications to monitor and protect power systems. The BD4850FVE-TR is designed to monitor the power supply voltage, input/output supply levels, battery level, and other power management functions.The BD4850FVE-TR application field and working principle facilitates system safety and reliability. Its main functionality is to provide power-supply monitoring and protection, as well as a watchdog timer to detect system malfunction and auto-reset the system. The BD4850FVE-TR monitors the power supply voltage and will notify the system if the voltage reaches an unwanted level. The monitored voltage level can be programmed with an internal register, which defines the trip points to alert the system.The BD4850FVE-TR can monitor and protect various types of output voltages, like logic regulators and processor voltages. It ensures that the processor voltage and other outputs remain within the optimal voltage range. If the voltage reaches a level below the minimum threshold, the BD4850FVE-TR will turn off the power line, thus protecting the system from damage or destruction. On the other hand, if the voltage exceeds the maximum threshold, the BD4850FVE-TR will send a shutdown signal to the system.The BD4850FVE-TR also comes with an embedded watchdog timer feature. The watchdog timer automatically reboots the system after a specified delay if it detects an abnormality in the system. This watchdog timer can be configured in two ways, either through manual programming or through software. The timer period can be adjusted according to the specific application.The BD4850FVE-TR also allows for an adjustable reset function. This reset function permits a system to be restarted without manual intervention. The duration of the reset can be programmed with an internal register, ensuring that the system resets after a certain amount of time.In summary, the BD4850FVE-TR application field and working principle is a simple, yet reliable, power management system that facilitates system reliability and safety. Its monitoring and protection functions ensure that the system remains within its optimum operating range, and its watchdog timer and reset function allow for automatic system rebooting in case of malfunction or unexpected conditions.
