M54545L
BI-DIRECTIONAL MOTOR DRIVER
DESCRIPTION
The M54545L, BI-DIRECTIONAL MOTOR DRIVER, consists
of a full bridge power driver designed for D-C motor control.
FEATURES • Wide operating voltage range (Vee = 3 -16V)
• Low output saturation voltage • Integral diodes for transient suppression
• 1.2A output current • Braking mode input • Low standby current
APPLICATION
Audio, video cassette recorder
FUNCTION
The M54545L, full bridge motor driver, has the logic circuitry and the quasi-darlington power driver for bidirectional control of D-C motors operating at currents up to 1, 2A. A braking mode by switching the both inputs high may make easier to control the motor. The power supplies for the logic circuitry, the predrivers and the power drivers are separated so that the application circuit with the M54545L can be easily optimized for lower power consumption.
