描述 Description

The IS31FL3723 is a general purpose 12×16 LEDs matrix driver with 1/12 cycle rate. The device can be programmed via an I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM data which allowing 256 steps of linear dimming.

Each LED open and short state can be detected, IS31FL3723 store the open or short information in Open-Short Registers. The Open-Short Registers allowing MCU to read out via I2C compatible interface. Inform MCU whether there are LEDs open or short and the locations of open or short LEDs.

The IS31FL3723 operates from 2.7V to 5.5V and features a very low shutdown and operational current.

IS31FL3723 is available in QFN-48 (6mm×6mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.
