MAX6974ATL Description

Short technical summary and product information.

The MAX6974ATL from Analog Devices is a precision current-sinking, 24-output PWM LED driver. It is engineered for applications such as full-color graphic message boards and video displays. Each of the 24 outputs offers individual 12-bit PWM intensity control for hue and 7-bit global PWM intensity control for luminance.

The device operates from a 3.0V to 3.6V logic supply and supports an LED power supply ranging from 3V to 7V. It provides constant output current calibration from 6mA to 30mA in 256 steps, allowing for precise color calibration. The MAX6974ATL features a high-speed, fully buffered, cascadable serial interface, open-circuit LED fault detection, and an optional watchdog timer.

With a 33MHz clock, it supports up to 63 frames per second for video applications. The driver has three banks of eight outputs, each intended for a different color in RGB applications. It can optionally multiplex to drive up to 48 LEDs using external PNP transistors.

The MAX6974ATL is available in a 40-pin TQFN package and operates within a temperature range of -40°C to +125°C. Its design facilitates cascading multiple drivers without external buffers, simplifying complex display module designs.
