Three-Phase Brushless Motor Driver IC
LB1854M
Overview
The LB1854M is a three-phase brushless motor driver IC
and is optimal, in particular, for driving VCR capstan and
drum motors.
Features
120° voltage linear drive technique
The LB1854M soft switching scheme allows smaller
external capacitors to be used (e.g., chip capacitors).
Built-in thermal-shutdown function
Built-in overcurrent protection circuit
Built-in FG amplifiers (operational amplifier and
Schmitt amplifier)
Control start voltage set by an external voltage
The output current feedback level can be changed by
changing the control gain to one of two levels.
