LB11660RV-TLM-H
数据手册.pdf1-Phase Fan Motor Driver 16Pin SSOP T/R
The LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD lock detection output pin and the LB11660FV the FG rotational speed detection output pin, respectively.
