Datasheet
Overview
The CMD1668M Series are 2-phase unipolar drive brushless
motor drivers that feature a wide usable voltage range and
a minimal number of required external components. They
also support the formation of motor lock protection and
automatic recovery circuits.
Functions and Features
• Output protection Zener diodes with variable breakdown
• Can support both 12-V and 24-V power supplies by
• Hall elements can be connected directly.
• 1.5-A output current output transistors built in
• Built-in rotation detection function that outputs low
• FG signal function that sets FG high when IN- is low,
• Motor lock protection and automatic recovery functions
• Thermal shutdown function
* All specs and applications shown above subject to change without prior notice.
