IS31FL3733B
DESCRIPTION
FEATURES
The IS31FL3733B is a general purpose 12×16 LEDs matrix driver with 1/12 cycle rate. The device can be programmed via an I2C patible interface. Each LED can be dimmed individually with 8-bit PWM data which allowing 256 steps of linear dimming.
IS31FL3733B features
3 Auto Breathing Modes which are noted as ABM-1, ABM-2 and ABM-3. For each Auto Breathing Mode, there are 4 timing characters which include current rising / holding / falling / off time and 3 loop characters which include Loop-Beginning / Loop-Ending / Loop-Times. Every LED can be configured to be any Auto Breathing Mode or No Breathing Mode individually.
Additionally each LED open and short state can be detected, IS31FL3733B store the open or short information in Open-Short Registers. The Open-Short Registers allowing MCU to read out via I2C patible interface. Inform MCU whether there are LEDs open or short and the locations of open or short LEDs.
The IS31FL3733B operates from 2.7V to 5.5V and features...
