IS31FL3745 - 18x8 DOTS MATRIX LED DRIVER

General Description

The IS31FL3745 is a general purpose 18×n (n=1~8) LED Matrix programmed via 1MHz I2C compatible interface.

Each LED can be dimmed individually with 8-bit PWM data and 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and 256 steps of DC current adjustable level.

Key Features

  • a very low shutdown and operational current. IS31FL3745 is available in WLCSP-36 (2.93mm×2.93mm, 0.5mm ball pitch, 0.25mm ball diameter) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C. October 2018.

IS31FL3745 18×8 DOTS MATRIX LED DRIVER GENERAL DESCRIPTION The IS31FL3745 is a general purpose 18×n (n=1~8) LED Matrix programmed via 1MHz I2C compatible interface. Each LED can be dimmed individually with 8-bit PWM data and 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and 256 steps of DC current adjustable level. Additionally each LED open and short state can be detected, IS31FL3745 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 IS31FL3745 operates from 2.7V to 5.5V and features a very low shutdown and operational current. IS31FL3745 is available in WLCSP-36 (2.93mm×2.93mm, 0.
