MAX6957ATL+

Display Drivers Overview

The MAX6957ATL+ is an LED display driver manufactured by Analog Devices Inc./Maxim Integrated, housed in a TQFN-40 package. It supports a supply voltage range of 2.5 V to 5.5 V and operates within a temperature range of -40°C to +125°C. The device features a 4-wire serial interface and drives up to 28 segments or 20 ports with a low-level output current of 18 mA. Maximum supply current is 230 µA, with power dissipation rated at 2.963 W.

Display Drivers Feature Summary

• Supports 4-wire serial interface for simplified control connections
• Configurable for driving multiple segment and digit combinations
• Includes global intensity control capabilities

Display Drivers Applications

• LED display systems requiring multi-segment configuration
• Portable electronic devices utilizing low-power display drivers
• Industrial instrumentation with wide temperature operational requirements

Display Drivers Procurement Notes

Verify the specific suffix TL indicates the TQFN-40 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check availability as distribution may be restricted in certain regions. Ensure the component matches the required thermal dissipation specifications for the target application environment.

Display Drivers Selection Notes

Select this model for applications requiring a compact surface-mount footprint with high pin count. Compare against the AAX variant if SSOP-36 packaging is preferred instead of TQFN-40. Consider the 18 mA sink capability for direct LED driving without external transistors. Verify interface compatibility with the host microcontroller's serial protocols.

Display Drivers Part Context

Part of the MAX6957 family of static LED drivers designed for flexible display configurations. The series offers constant current outputs suitable for various LED types. This specific TL variant provides a leaded quad flat no-lead package option for dense PCB layouts.

Display Drivers Replacement Considerations

MAX6957AAX+T serves as a package alternative offering identical electrical functionality in an SSOP-36 housing.
