Краткое описание:
54-Channel LED Driver with 8-bit PWM and 8-bit DC Current Control
Дополнительная информация
The IS31FL3254 is a 54-channel constant current LED driver with a 1MHz I2C compatible interface. Each of the 54 channels can be dimmed individually with 8-bit PWM data and 8-bit DC scaling data, allowing 256 steps of linear PWM dimming and 256 steps of DC current adjustment. It operates from a supply voltage range of 2.7V to 5.5V and features very low shutdown and operational current. The device includes individual open and short LED detection, which is stored in registers and can be read by a microcontroller.
