Monolithic Digital IC
LB1642
Bidirectional Motor Driver with
Braking Function
Overview
The LB1642 is a bidirectional motor driver IC. It is
especially suited for use in motor drive applications
where the arm control function of players and the auto
reverse function of cassette decks are performed.
Features
• On-chip braking function.
• On-chip diode to absorb dash current.
• Wide operating voltage range (4 to 16V).
• Direct drivable with TTL.
