Quick-Start Guide

Selecting the Appropriate Driver

The MAX6960–MAX6963 matrix LED drivers are avail-

able in four versions, with different levels of functionality

(Table 1). The two-part ID bits in the fault and device ID

face software. The ID bits may be of use if the same

panel software is used to drive more than one type of

display panel, because the software can automatically

detect the panel type.

This data sheet uses the generic name MAX6960 to

refer to the family of four parts MAX6960 through

MAX6963, unless there is a specific difference to

discuss.

The purpose of this quick-start guide is to provide an

overview of the capabilities of the MAX6960 so that the

driver can be easily evaluated for a particular applica-

tion, without fighting through a complex data sheet.

Terminology

• Pixel: One “point” on a display. Comprises one LED

for a monocolor display, two LEDs for an RGY dis-

play, and three LEDs for an RGB display.

• Monocolor: Display has only one color, typically red

for low-cost signs or orange for traffic signs. Varying
