MAXIM INTEGRATED / ANALOG DEVICES MAX6957AAI LED Driver and I/O Expander
The MAX6957AAI+ is a versatile 20-port LED display driver and I/O expander, featuring a 4-wire interface and operating within a voltage range of 2.5V to 5.5V. Packaged in a 28-pin SSOP, each port can be individually configured as a logic input, logic output, or common-anode LED segment driver. When used as an LED driver, it functions as a digitally controlled constant current sink with 16 adjustable current steps ranging from 1.5mA to 24mA, suitable for discrete LEDs and common-anode numeric or alphanumeric displays. As a GPIO, ports can serve as push-pull outputs capable of sinking 10mA and sourcing 4.5mA, or as Schmitt trigger inputs with optional internal pull-ups. Seven ports include configurable transition detection logic to generate interrupts on level changes. The device supports high-speed serial interfaces such as SPI, QSPI, or MICROWIRE at 26MHz and features an operating temperature range from -40°C to 125°C. It consumes a maximum shutdown current of 11µA and offers 16-step programmable LED current control. Applications include power management, industrial systems, and system monitoring. Please note that market demand has extended lead times, and delivery dates may fluctuate; this product is exempt from discounts.
