BD2066FJ-E2

The BD2066FJ-E2 device is a single-channel power supply controller that is part of a range of power management products, which are used for controlling power distribution in the electronics industry. It is categorized as a PMIC (Power Management Integrated Circuit) and is part of the Power Distribution Switches, Load Drivers category. The BD2066FJ-E2 is able to perform high-accuracy voltage detection and power control as well as have flexible protection functions to ensure the accuracy of systems.

The application fields of the BD2066FJ-E2 are home audio amplifier systems, car cooling fans, battery chargers and medical equipment. Additionally, the device functions well in automotive applications such as fuel pumps, engine control modules and airbag systems. As an added benefit, the device is RoHS compliant, making it an ideal choice for use in industrial and automotive applications.

The BD2066FJ-E2 features an integrated analog circuit that allows for power control with approximately +/- 1.0 % accuracy. The device is designed to support a single-channel output up to 7A of current draw, while supporting voltages up to 100V. It has two protection channels which detect over-current, over-voltage or under-voltage conditions and allows for adjustable time delays before shutting down the power supply. The device also includes a power monitor which is able to monitor voltage and current, providing vital troubleshooting information.

The working principle of the BD2066FJ-E2 is based on its versatile power management functions. It is capable of controlling the on/off switching of the power supply through a set of 2 logic inputs and 2 logic outputs (DV_MTR, DHS_EN and DHS_FAIL). When in normal operation, the device sets the DV_MTR line high, indicating a valid output voltage. The DHS_EN is pulled low while DHS_FAIL is pulled high to indicate a safe power-up state. If the device undergoes an overcurrent or overvoltage condition, the DV_MTR line will be pulled low to indicate an INVALID output voltage, while DHS_FAIL is pulled low and DHS_EN is pulled high to indicate a shutdown state. The protection channels also allow the device to be configured to support a higher current draw, allowing more robust operation and more flexibility in terms of application.

In conclusion, the BD2066FJ-E2 is an ideal solution for power management in the industrial and automotive sectors. Its versatile protection functions, high accuracy power control, and power monitor provide reliable and safe operation. The device has wide application fields and is RoHS compliant, making it a good choice for implementing and extending power distribution solutions.
