MAX6959AAEE+ Description

Short technical summary and product information.

The MAX6959AAEE+ is a compact, multiplexed common-cathode display driver designed to interface microprocessors with seven-segment numeric LED digits and discrete LEDs. It utilizes an SMBus™ and I²C-compatible 2-wire serial interface, supporting 2.5V and 3.3V systems when powered from a 5V supply.

 

This driver can control up to four 7-segment digits with decimal points, plus four discrete LEDs, or up to 36 discrete LEDs if decimal points are not used. The MAX6959 variant includes two input ports configurable as a key-switch reader, capable of scanning and debouncing up to eight switches.

 

Key features include a hexadecimal font, multiplex scan circuitry, anode and cathode drivers, and static RAM for digit storage. The peak segment current is internally set to 23mA, with a 64-step digital brightness control for intensity adjustment. It operates from 3V to 5.5V and is available in a 16-QSOP package, specified for the -40°C to +125°C automotive temperature range.

 

The LED drivers are slew-rate-limited to reduce EMI. The device also includes a low-power shutdown mode (20µA with data retained), a scan-limit register for controlling the number of displayed digits, and a test mode. The surface mountable 16-SSOP package (0.154", 3.90mm Width) is suitable for various applications.
