The BD4840FVE-TR is an electronic component within the PMIC (Power Management Integrated Circuit) product family known as Supervisors. As a supervisor, the BD4840FVE-TR functions as an integrated condition monitor, providing over-voltage, under-voltage, and over-temperature protection for power-supply systems. In addition to these protection features, the BD4840FVE-TR can monitor multiple power rails, providing a real-time indication of the system’s power status.

The BD4840FVE-TR output voltage is factory-set and can be adjusted from 3.3V to 5.5V using an external resistor divider. This makes the device extremely versatile, as it can be used in any system with a voltage between 3.3V and 5.5V. In addition, the BD4840FVE-TR features an adjustable hysterisis voltage range from 0.2V to 6.0V. Hysterisis helps to prevent false triggering and ensure accurate protection under varying operating conditions.

The BD4840FVE-TR is a low-power device, consuming only 2µA under normal operation, and features an enable/disable pin that allows the user to quickly power down the device. The BD4840FVE-TR also features a reset output that can be used to reset the system when an over-voltage, under-voltage, or over-temperature condition is detected. This reset output can be connected to a microcontroller, allowing the system to take appropriate actions once a condition has been detected.

The BD4840FVE-TR is ideal for use in computer systems, network appliances, and automotive applications. The device’s low-power consumption, adjustable hysterisis voltage range, and enable/disable pin make it an ideal choice for power-supply monitoring and protection. Its reset output makes it even more versatile, as it can be used to notify the system when a potential problem is detected.

To sum up, the BD4840FVE-TR is a versatile, low-power electronic component that is designed to provide over-voltage, under-voltage, and over-temperature protection for power-supply systems. Its adjustable output voltage, adjustable hysterisis voltage range, enable/disable pin, and reset output make it an ideal choice for systems that require accurate and reliable power-supply monitoring and protection.
