MAX6957AAI+

Display Drivers Overview

The MAX6957AAI+ is an LED display driver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-SSOP package. It supports 7-digit displays with up to 28 segments and features a 4-wire serial interface. The device operates on a supply voltage ranging from 2.5 V to 5.5 V, with a maximum power supply current of 230 µA. It provides a low-level output current of 18 mA per port and handles a power dissipation of 727 mW. The component functions within a temperature range of -40°C to +125°C.

Display Drivers Feature Summary

• Supports multiplexed LED displays with configurable segment and digit configurations
• Integrates constant-current control for uniform brightness across all ports
• Utilizes a standard 4-wire serial interface for simplified system connectivity

Display Drivers Applications

• Static LED numeric displays
• Multiplexed alphanumeric indicators
• Consumer electronics status panels

Display Drivers Procurement Notes

Verify the specific suffix and package variant against the design specification before ordering. Confirm availability status as distribution channels may report limited stock or discontinuation. Ensure the selected component matches the required operating temperature range and interface timing requirements for the target application environment.

Display Drivers Selection Notes

Select this component when a dedicated LED driver with integrated constant-current regulation is required. It is suitable for designs needing a compact solution for driving multiple digits without external current-limiting resistors. Consider the 28-SSOP footprint constraints and the 4-wire interface compatibility with the host microcontroller.

Display Drivers Part Context

This part belongs to the MAX6957 series of LED display drivers from Maxim Integrated. It is designed to replace discrete driver solutions, reducing board space and component count. The series offers various pinout options and package types to accommodate different display densities and form factors in embedded systems.

Display Drivers Replacement Considerations

Check for MAX6957 variants with different package codes such as AAX for SSOP-36. Verify electrical compatibility with MAX6956 if segment count requirements differ.
