IS31FL3733B Overview
Key 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 compatible 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
- Every LED can be configured to be any Auto Breathing Mode or NoBreathing 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 compatible 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 a very low shutdown and operational current
- It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C
