MAX6953EAX+T

Display Drivers Overview

The MAX6953EAX+T is a compact cathode-row display driver designed to interface microprocessors with 5x7 dot-matrix LED displays via an I2C-compatible serial interface. It supports operation within a voltage range of 2.7V to 5.5V and drives up to four digits, totaling 140 LEDs. The device features a 400kbps 2-Wire Interface, built-in ASCII font for 104 characters, and 24 user-definable character slots. Key electrical parameters include a maximum supply current of 15mA, high-level output current of 50mA, low-level output current of 500mA, and power dissipation of 941.2mW. It operates between -40°C and +85°C and is housed in an SSOP-36 package.

Display Drivers Feature Summary

• Supports automatic blinking control for each segment and 16-step digital brightness adjustment
• Includes slew-rate-limited segment drivers to reduce electromagnetic interference
• Provides low-power shutdown mode retaining data with 70µA consumption
• Blanking function activates automatically during power-up

Display Drivers Applications

• Driving 5x7 dot-matrix LED graphic panels
• Building multi-digit alphanumeric display systems
• Microprocessor-based indicator interfaces

Display Drivers Procurement Notes

Verify the specific suffix against official documentation, as standard datasheets typically list the MAX6953EAX+ in tube packaging. Confirm if the 'T' suffix denotes tape-and-reel availability or a variant configuration directly from Analog Devices/Maxim Integrated before ordering. Ensure compatibility with existing PCB footprints for the SSOP-36 package.

Display Drivers Selection Notes

Select this component when interfacing with 5x7 matrix displays requiring I2C connectivity. Consider the 500mA low-level sink capability for driving multiple segments simultaneously. Evaluate the thermal performance given the 941.2mW power dissipation rating in the SSOP-36 package for enclosed designs.
