M54548L

MITSUBISHI BIPOLAR DIGITAL ICs M54548L BI-DIRECTIONAL MOTOR DRIVER WITH MOTOR SPEED CONTROL DESCRIPTION The M54548L, BI-DIRECTIONAL MOTOR DRIVER, consists of a full bridge power driver designed for use in a D-C motor control circuit. The internal operational amplifier is capable for controlling the voltage across the bridge outputs, FEATURES Wide operating voltage range NMOS and CMOS compatible input 1. 2A output current Integral operational amplifier for output source voltage Output transient suppression Braking mode input APPLICATION Audio, video cassette recorder FUNCTION The M54548L, full bridge motor driver, has the logiC circuitry and the quasi-darlington power driver for bidirectional control of D-C motors operating at current up to 1. 2A. The inputs, S1, S2 and S3, are capable to control the bridge output polarity and also to select the supply voltage of the predriver from the voltages drived by V1, V2 or the output of the operational amplifier.
