The MAX6966ATE from Maxim Integrated is a versatile and advanced LED driver and I/O expander that is designed to cater to a wide range of applications requiring high-performance control of LED arrays and other output devices. This compact, highly integrated component is engineered to operate with a 2-wire, I²C-compatible serial interface, making it an ideal solution for applications where space and interface simplicity are at a premium.

Key Features

• Integrated LED Driver: With 10 ports that can be individually configured as either open-drain constant-current LED drivers or as general-purpose I/Os (GPIO), this device provides flexibility for various design needs.
• Constant-Current Sinking: The constant-current outputs are designed to sink up to 55mA, with the current value easily set by a single external resistor, simplifying design and reducing component count.
• PWM Intensity Control: Each LED output can be individually adjusted with 8-bit pulse-width modulation (PWM), enabling precise control over LED brightness and creating sophisticated lighting effects.
• Transition Detection: The MAX6966ATE can detect transitions on the inputs when configured as GPIOs, a feature that is particularly useful for interfacing with mechanical switches or sensors without the need for continuous polling.
• Thermal Protection: Built-in thermal shutdown protection ensures the device operates within safe temperature limits, enhancing the longevity and reliability of the application.
