概觀

The IS32FL3738 is a general purpose 6×8 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 × 4 PWM data which allowing 512 steps of linear dimming. IS32FL3738 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, IS32FL3738 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 IS32FL3738 operates from 2.7V to 5.5V and features a very low shutdown and operational current. IS32FL3738 is available in eTSSOP-28 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.
