The IS31FL3743A is a general purpose 18×n (n=1~11) 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, IS31FL3743A store.
a very low shutdown and operational current.
IS31FL3743A 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.
