ON Semiconductor NSI45060JDT4G Constant Current Regulator

The NSI45060JDT4G from ON Semiconductor is a robust, high-performance constant current regulator (CCR) designed for driving current in LEDs. This device is engineered to provide a cost-effective solution for regulating current over a wide voltage range. It is highly suitable for automotive, industrial, and general lighting applications where consistent illumination and reliability are paramount.

With a fixed current regulation of 60mA, ±10%, the NSI45060JDT4G ensures a stable current flow to the LEDs, which helps in maintaining consistent brightness and color over time. The device is capable of withstanding a maximum voltage of 45V, making it versatile for various circuit configurations and ensuring the protection of LEDs against voltage surges.

The CCR's turn-on voltage is as low as 0.5V, with an operating range up to 45V, which provides flexibility in design for series or parallel LED configurations. Its high voltage capability also allows for multiple LEDs to be driven in series, thus reducing the complexity and cost of the driver circuit.

ON Semiconductor's NSI45060JDT4G comes in a compact SOD-123 package, which is ideal for space-constrained applications. Moreover, it is AEC-Q101 qualified, which means it has passed stringent reliability standards for automotive applications. The device also features a negative temperature coefficient, which reduces the output current as the temperature rises, thus providing an inherent thermal protection for the LEDs.

Thermal shutdown is another key feature of this CCR, ensuring the device turns off in the event of excessive heat, thereby protecting the circuit components from potential damage. Once the device cools down to a safe temperature, it will resume normal operation. This self-protecting feature enhances the longevity of both the regulator and the LEDs it drives.

In summary, the NSI45060JDT4G from ON Semiconductor is a reliable and efficient solution for driving LEDs with constant current in a variety of applications. Its robust design, thermal protection features, and compliance with automotive reliability standards make it a preferred choice for designers looking for a high-quality CCR.
