IS31FL3743B - 18x11 DOTS MATRIX LED DRIVER

General Description

The IS31FL3743B is a general purpose 18×n (n=1~11) LED Matrix programmed via 12MHz SPI 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. IS31FL3743B is available in UQFN-40 (5mm×5mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.

IS31FL3743B 18×11 DOTS MATRIX LED DRIVER WITH 12MHZ SPI April 2022 GENERAL DESCRIPTION The IS31FL3743B is a general purpose 18×n (n=1~11) LED Matrix programmed via 12MHz SPI 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 state can be detected, IS31FL3743B store the open information in OpenRegisters. The Open Registers allowing MCU to read out via SPI, inform MCU whether there are LEDs open or short LEDs. The IS31FL3743B operates from 2.7V to 5.5V and features a very low shutdown and operational current. IS31FL3743B is available in UQFN-40 (5mm×5mm) package. It operates from 2.7V to 5.
