M54547P
BI-DIRECTIONAL MOTOR DRIVER WITH OP AMP AND TRANSISTOR ARRAY
DESCRIPTION
The M54547P, BI-DIRECTIONAL MOTOR DRIVER, consists of a full bridge power driver and dual general purpose NPN darlington pairs.
FEATURES
• 600mA output current • Braking mode input • Integral operational amplifier at direction control input • Output transient suppression
APPLICATION
Audio, vid\:lo cassette recorder
FUNCTION
. The M54547P, full bridge motor driver, has the logic circuitry and darlington power drivers for bidirectional control of D-C motors operating at currents up to 600mA. The operational amplifier is connected to the direction control input through an analog switch controlled by pin 15 input. By switching the INAS input high and the IN, input low, the output of the amplifier appears at the output 0, so that the voltage across the bridge output is altered linearly by the amplifier input. The internal NPN darlington pairs are capable of sinking 300mA.
