LB1854M

Ordering number : EN4476B Monolithic Digital IC LB1854M Three-Phase Brushless Motor Driver IC Overview The LB1854M is a three-phase brushless motor driver IC and is optimal, in particular, for driving VCR capstan and drum motors. Package Dimensions unit: mm 3073A-MFP30S [LB1854M] 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.
