BD18353EFV-M
車載用 1ch 大電流LEDコントローラ
BD18353EFV-M/MUF-Mは1ch LEDコントローラです。ハイサイド電流検出アンプを内蔵しています。内蔵PWM生成回路により、PWM調光Dutyを自由に設定できます。PWM調光は外付けP-ch MOSFETを駆動することで実現しています。LEDの異常状態をFAULT_B端子に出力します。2系統のアナログ調光を内蔵しています。アナログ調光及びPWM調光設定用の高精度3.0V出力電源を内蔵しています。

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.
