Maxim Integrated MAX6956AAX/V+ Product Overview

The MAX6956AAX/V+ from Maxim Integrated is a versatile, serially interfaced LED display driver and I/O expander that is designed to minimize the complexity and number of components required to control up to 28 LED displays or discrete LEDs. This powerful device operates with a 2-wire, I²C-compatible serial interface, making it an ideal choice for applications where pin and board space is at a premium, such as handheld devices, industrial control panels, and LED-based signage.

With its wide supply voltage range of 2.7V to 5.5V, the MAX6956AAX/V+ is flexible enough to be used in both 3.3V and 5V systems. The device integrates a built-in 8-bit PWM intensity control for each LED, allowing for precise brightness control and the possibility to create sophisticated lighting effects without the need for external components.

The MAX6956AAX/V+ supports the control of both common-cathode and common-anode 7-segment displays, and it can drive up to 8 digits of 7-segment displays or a combination of segmented displays and discrete LEDs. This feature makes it a highly adaptable solution for a wide range of display requirements.

Key features of the MAX6956AAX/V+ include:

• Individual LED current control for uniform brightness
• Internal multiplexing circuitry with digit and segment drivers
• 28 output ports with constant-current sink capabilities
• Open-drain output option for discrete LEDs
• Programmable transition effects for eye-catching display changes
• Thermal shutdown and overvoltage protection for improved safety and reliability
• Compact 36-pin SSOP package for space-saving designs

Whether you're developing consumer electronics, automotive dashboards, or industrial control interfaces, the MAX6956AAX/V+ provides an efficient and elegant solution for controlling multiple LEDs with minimal I/O lines. Its integration of display driver and I/O expander functionalities, along with its robust protection features, makes it a smart choice for your next design project.
