• Low-noise: The CPT60145 is designed for low-noise operation, reducing interference from other electrical components in the system. This makes it ideal for automotive interior and exterior switch applications, as well as engine-controller modules.
• High switching frequency: The rectifier array is capable of operating at high frequencies, allowing for quick response times and increased efficiency. This makes it ideal for automotive body controllers.
• Accuracy: The rectifier array is designed to be highly accurate, providing consistent and reliable current levels. This makes it suitable for engine-controller modules and automotive interior and exterior switches.
• Low power consumption: The rectifier array is designed with low power consumption in mind, allowing for increased efficiency and reduced energy costs.

The CPT60145 is also designed to meet the stringent requirements of automotive standards, such as AEC-Q101 and UL. This ensures that it is reliable and able to withstand harsh automotive environments.

Working Principle

The CPT60145 is a highly integrated monolithic rectifier array consisting of one N-channel and one P-channel MOSFET, as well as sixteen low-voltage p-n rectifiers. The array is designed for low-voltage, low-frequency applications and uses flyback topology for power conversion.The N-channel MOSFET is the primary power switch of the rectifier array and is responsible for controlling the current flow through the LEDs. The P-channel MOSFET is responsible for providing a return path for the current flow. The sixteen p-n rectifiers are used to convert the AC voltage into DC voltage and also act as current limiters.The CPT60145 also features inherent safety features, such as overvoltage and reversed-polarity protection. The overvoltage protection is designed to limit the output voltage in the event of an overvoltage condition. The reversed-polarity protection prevents the rectifier array from operating in an incorrect direction. Additionally, the rectifier array is designed with thermal-overload protection, ensuring that it can operate safely and reliably in a variety of automotive environments.

Conclusion

The CPT60145 is a highly integrated rectifier array for low-voltage DC applications, designed for the most demanding automotive applications. The rectifier array is designed for low-noise operation, high switching frequency, accuracy, and low power consumption, and meets the stringent requirements of automotive standards. The array consists of one N-channel and one P-channel MOSFET, in addition to sixteen p-n rectifiers. The rectifier array is also designed with safety features, such as overvoltage, reversed-polarity, and thermal-overload protection. With its versatile design and inherent safety features, the CPT60145 is an ideal solution for a variety of automotive applications.
