The MAX6979AUG+ is a versatile LED driver IC designed for lighting and signage applications. It features 16 open-drain, constant-current-sinking outputs, each capable of handling up to 55mA and rated for 5.5V. The device operates from a wide supply voltage range of 3V to 5.5V, allowing flexibility in power design. The output current for all channels is programmed together using a single external resistor, simplifying component selection.
This LED driver utilizes an industry-standard, 4-wire serial interface operating at up to 25Mb/s, enabling easy integration with microcontrollers. It includes advanced features such as automatic detection of open-circuit LEDs, reporting fault status via the serial interface. For safety-critical applications, a fail-safe feature blanks the display if the serial interface becomes inactive for more than 1 second, automatically turning off all LEDs.
The MAX6979AUG+ is housed in a 24-TSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to +125°C, making it robust for various environmental conditions. The device offers 3% current matching between outputs and 6% current matching between ICs, ensuring consistent LED illumination.
