ON Semiconductor CAT4016HV6-T2 LED Driver IC

The CAT4016HV6-T2 from ON Semiconductor is a high-performance, 16-channel constant-current sink LED driver designed for a variety of lighting applications. This integrated circuit (IC) is ideal for driving LEDs with precision and efficiency, ensuring consistent brightness and extending LED life. It is particularly suitable for LED billboards, display backlighting, and general-purpose LED lighting systems.

With its 16 individually regulated current sinks, the CAT4016HV6-T2 can support up to 16 LEDs with a maximum current of 120 mA per channel. The current sinks can be paralleled for higher current applications, providing designers with flexibility in their lighting designs. The LED current is set by an external resistor, allowing for easy adjustment to accommodate different LED types and configurations.

The device operates over a wide input voltage range from 3V to 5.5V, making it compatible with various power supplies and suitable for battery-operated devices. It also features a high-voltage version that can withstand up to 17V on the output, enabling the driving of more LEDs in series per channel and reducing the number of required ICs in high LED count designs.

The CAT4016HV6-T2 incorporates a 4-wire serial interface with a clock speed of up to 25 MHz for data input, which allows for seamless integration with microcontrollers or other control units. This interface provides not only control over the individual LED channels but also enables the implementation of dimming and advanced lighting effects.

To ensure reliable and safe operation, the device includes built-in thermal shutdown protection and open LED detection. These features protect the IC and the LEDs from damage due to overheating or open-circuit conditions. The CAT4016HV6-T2 is available in a thermally enhanced 24-lead TSSOP package, which helps in heat dissipation and allows for compact PCB layouts.

In summary, the CAT4016HV6-T2 LED driver from ON Semiconductor is a versatile and robust solution for controlling multiple LEDs with precision. Its integration of key features and protections makes it an excellent choice for designers looking to create efficient and reliable LED lighting systems.
