The IS31FL3746B is a general purpose 18×n (n=1~4) 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, IS31FL3746B store the open information in Open- Registers. The Open Registers allowing MCU to read out via SPI, inform MCU whether there are LEDs open or short LEDs. The IS31FL3746B operates from 2.7V to 5.5V and features a very low shutdown and operational current. IS31FL3746B is available in QFN-32 (4mm×4mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.
