The UCC3972PWG4 is an integrated light ballast controller, featuring a high-energy efficiency design for light ballast applications. This device provides accurate current mode over-voltage and over-current protection for light ballast applications. It also features low current consumption and high accuracy protection from leakage currents and operating temperature.

The UCC3972PWG4 is designed to improve the energy efficiency of light ballast applications, including high-efficiency fluorescent lamps, halogen lamps, and incandescent lamps. Its multiple independent current limits and over-voltage protection are designed to increase energy efficiency by eliminating excess current drawn and voltage surges. The device also features an adjustable startup delay, which helps to reduce switching surge and provide a more stable operating environment.

The device is integrated with a high efficiency current output stage that controls the ballast current accurately and precisely. The output stage operates in both linear and pulse width modulation modes, which provides flexibility to ensure compatibility with different ballast types. The device also features an adjustable soft-start feature, which helps reduce inrush currents and improve circuit protection.

The UCC3972PWG4 also features over-voltage and over-current protection. The over-voltage protection prevents the ballast from experiencing voltage too high that may cause damage to components or cause the ballast to malfunction. The over-current protection will shut down the ballast at a predetermined current threshold and prevent overload or short-circuit conditions.

In addition, the UCC3972PWG4 features a low quiescent current of 5mA, making it ideal for applications that require battery-powered operation. The device also features a protection clamp for protection from over-voltage and surge events, as well as low EMI for minimal interference with nearby electric signals. The device also features integrated thermal protection to protect it from excessive temperatures.

The UCC3972PWG4 is an ideal light ballast controller for applications requiring improved accuracy and efficiency. Its features make it suitable for a wide range of applications including high-efficiency fluorescent lamps, halogen lamps, and incandescent lamps. Its over-voltage and over-current protection make it a reliable solution when it comes to energy efficiency and circuit protection. Its integrated protection mechanisms and low quiescent current make it an excellent choice for battery-powered applications.
