IS31FL3743B - Lumissil

IS31FL3743B 18x11 DOTS MATRIX LED DRIVER

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 informatio.
