Краткое описание:
48-Channel LED Driver with 16-bit PWM Engine and 33MHz Serial Interface
Дополнительная информация
The IS32FL3248 is a 48-channel constant current LED driver designed for automotive and industrial control panels. It features a 16-bit PWM engine for fine dimming and 64 steps of global current adjustment. The device supports a high-speed 33MHz serial interface and includes programmable algorithms to minimize audible noise from MLCC decoupling capacitors. It provides real-time LED open and short detection along with over-temperature protection. The automotive ‘32’ version is typically AEC-Q100 qualified for high-reliability applications.
