M54549L
M54549L is BI-DIRECTIONAL MOTOR DRIVER manufactured by Mitsubishi Electric.
DESCRIPTION
The M54549L, DUAL BI-DIRECTIONAL MOTOR DRIVER, consists of two separated full bridge power drivers designed for use in a D-C motor control circuit.
FEATURES
- Two separated full bridge driver
- Wide operating voltage range (Vee =4-16V)
- TTL, PMOS and CMOS patible input
- Low output saturation voltage
- Integral diodes for transient suppression
- 2A output current
- Braking mode input
- Internal thermal shutdown protection
APPLICATION
Audio, video cassette recorder
FUNCTION
The M54549L, dual full bridge power drivers, has the logic circuitry and dual quasi-darlington power drivers for bidirectional control of D-C motors operating at currents up to 1.2A. The input 8E selects the one of the bridges and the inputs 8, and S2 determines the output polarity of the designated bridge.
