The MAX6975ATL+ is a precision current-sinking, 24-output PWM LED driver designed for full-color graphic message boards and video displays. Each output offers individual 14-bit PWM intensity control and 5-bit global PWM intensity control. The device supports a full-scale current adjustable from 6mA to 30mA in 256 steps for precise color calibration.
This LED driver operates from a 3.0V to 3.6V logic supply and can handle an LED power supply ranging from 3V to 7V. It features a high-speed, fully buffered, cascadable serial interface with differential signaling for improved signal integrity and reduced EMI. The MAX6975ATL+ includes open-circuit LED fault detection and an optional watchdog timer that blanks the display if signal inputs fail to toggle.
Available in a 40-pin TQFN package, the MAX6975ATL+ is suitable for surface mount applications. It operates within a wide temperature range of -40°C to +125°C, making it ideal for demanding environments. The device can optionally multiplex to drive up to 48 LEDs using external PNP transistors.
Key applications include LED video display panels, LED message boards, and variable message signs.
