Maxim Integrated MAX6957ATL+T Product Overview

The Maxim Integrated MAX6957ATL+T is a sophisticated LED display driver and I/O expander designed to minimize the complexity and power requirements of interfacing with alphanumeric displays. This high-performance device is particularly suitable for applications that require the control of multiple LEDs, such as industrial control systems, panel meters, and portable instruments.

Key Features

• Integrated LED Driver: The MAX6957ATL+T can drive up to 20 or 28 seven-segment, 14-segment, or 16-segment alphanumeric characters, or up to 140 or 196 individual LEDs, providing designers with a versatile solution for display management.
• I/O Expander Functionality: It includes I/O expander capabilities, allowing it to interface with microprocessors or microcontrollers, thereby reducing the number of pins needed for LED display management.
• Serial Interface: The device uses a 2-wire, I²C-compatible serial interface, which simplifies the connection to the host controller and enables easy cascading of multiple devices without the need for complex wiring.
• Individual LED Control: Each LED can be individually controlled, dimmed, or blinked, offering a high degree of flexibility for creating dynamic lighting effects and enhancing user interfaces.
• Low Power Consumption: Designed with power efficiency in mind, the MAX6957ATL+T operates within a supply voltage range of 2.7V to 5.5V, making it suitable for battery-powered applications.
• Built-in Key Scan: The device includes a built-in key scan circuitry which can scan up to 64 switches, thus reducing the processing burden on the host controller.
• Package Options: It is available in a 40-pin thin QFN (TQFN) package, offering a compact footprint for space-constrained applications.
