BD18353EFV-M
오토모티브용 1ch 대전류 LED 컨트롤러
BD18353EFV-M/MUF-M은 1ch LED 컨트롤러입니다. High-side 전류 검출 앰프를 내장하고 있습니다. 내장 PWM 생성 회로를 통해, PWM 조광 Duty를 자유롭게 설정할 수 있습니다. 외장 Pch MOSFET를 구동함으로써 PWM 조광을 실현합니다. LED의 이상 상태를 FAULT_B 단자로 출력합니다. 2계통의 아날로그 조광을 내장하고 있으며, 아날로그 조광 및 PWM 조광 설정용의 고정밀도 3.0V 출력 전원을 내장하고 있습니다.

This Evaluation Board was developed for ROHM’s LED Driver BD18353EFV-M. BD18353EFV-M is a 1ch LED Controller. High side current detection amplifier is built-in. PWM dimming duty can be freely set with built-in PWM generation circuit. PWM dimming realizes by driving an external P-ch MOSFET. Outputs abnormal LED status to the FAULT_B pin. Two systems of analog dimming are built-in. High precision 3.0V output power supply for analog dimming and PWM dimming setting is built-in.
