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
register (Table 32) identify the driver type to the inter-
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
