Maxim Integrated MAX6956ANI Product Overview

The MAX6956ANI from Maxim Integrated is a sophisticated 2-wire interfaced LED display driver and I/O expander that is designed to efficiently control up to 28 segments of LEDs. This integrated circuit (IC) is housed in a 40-pin SSOP (Shrink Small Outline Package) which provides a compact footprint for space-constrained applications. The MAX6956ANI is a versatile solution for driving both discrete LEDs and 7-segment numeric displays, making it an ideal choice for a wide range of applications including industrial control panels, message boards, and instrumentation displays.

Key Features

• Multiple LED Control: With the ability to control up to 20 individual LEDs or 5 digits of 7-segment displays, the MAX6956ANI provides a flexible platform for creating dynamic and informative display interfaces.
• 2-Wire Interface: The device uses an I2C-compatible serial interface which simplifies connection to microcontrollers and allows multiple devices to be connected on the same bus, reducing wiring complexity.
• Intensity Control: Each LED can be individually adjusted for brightness with 16 levels of intensity, allowing for nuanced and eye-catching displays that can be easily read in various lighting conditions.
• Key Scan: A built-in key scan feature enables the IC to detect inputs from up to 8 mechanical switches, reducing the need for additional input handling circuitry.
• Transition Detection: The MAX6956ANI can detect changes in switch state, which is valuable for applications requiring responsive user interfaces.
