Part Overview
Description
The MAX6957 is a compact, serial-interfaced LED display driver and general-purpose I/O (GPIO) peripheral that provides microprocessors with up to 28 ports. Each port is individually configurable as either a logic input, logic output, or common-anode (CA) LED constant-current segment driver. The LED drivers are suitable for both discrete LEDs and CA numeric and alphanumeric LED digits. Each port configured as a GPIO can be either a push-pull logic output or a Schmitt logic input with optional internal pullup. Seven ports feature configurable transition detection logic, which generates an interrupt upon change of port logic level. The MAX6957 is controlled through an SPI-compatible 4-wire serial interface.
Features
High-Speed 26MHz SPI-/QSPI™-/MICROWIRE®-Compatible Serial Interface
2.5V to 5.5V Operation
-40°C to 125°C Temperature Range
20 or 28 I/O Ports, Each Configurable as:
Constant-Current LED Driver
Push-Pull Logic Output
Schmitt Logic Input
Schmitt Logic Input with Internal Pullup
11μA (max) Shutdown Current
16-Step Individually Programmable Current Control for Each LED
Logic Transition Detection for Seven I/O Ports
Applications
Set-Top Boxes
Panel Meters
White Goods
Bar Graph Displays
Industrial Controllers
System Monitoring
