The UC3872DW is an integrated power management and protection circuit designed specifically for high brightness lighting applications. It is designed to provide a wide variety of protection functions, including over-current, over-voltage, brown-out, reverse polarity and open-circuit protection. In addition, it also provides supply regulation, voltage monitoring and fault detection.
The UC3872DW is a dual-output power management and protection IC whose primary function is to switch between two high-power lighting outputs at a pre-defined power level that is driven by an external power MOSFET. When enabled, the IC will automatically turn on both outputs, providing maximum available power from the transformer. When the current draw from both outputs reaches the set, the IC will turn off one of the outputs, reducing the current draw to the set power level. This feature helps to maintain optimal system performance and also reduce energy usage, resulting in a longer operating life for both the transformer and LED.
The UC3872DW also provides over-current protection features. It can detect and shut off both outputs in the event of an over-current event, protecting the system from damage. The IC also offers over-voltage protection, allowing it to detect both low and high voltage levels. Once the voltage exceeds certain predefined limits, the output will be shut off and the system can be reset.
The UC3872DW also offers reverse polarity protection, allowing it to detect and protect against incorrect wiring of the outputs. An open-circuit protection feature is also included, helping to prevent damage to the MOSFETs used in high-power LED applications. Additionally, the UC3872DW offers voltage monitoring capabilities, allowing it to detect voltage irregularities, such as brown-outs, and provide protection against potentially damaging power losses.
The UC3872DW is a powerful and versatile integrated power management and protection circuit, suitable for a wide variety of lighting applications. It offers a variety of features to ensure safe and reliable operation, and its advanced features reduce power consumption and extend the life of LEDs and other related components. With its dual output and multiple protection functions, it is an ideal choice for applications demanding a reliable and robust power solution.
