Monolithic Linear IC

Low-Voltage DC Motor Speed Controller

with Logic Circiuit

Ordering number:ENN1402D

LA5550, 5550M

SANYO Electric Co.,Ltd. Semiconductor Company

TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN

Applications

The LA5550, 5550M are low-voltage (3V min.) DC
motor speed control IC with bidirectional driver and
logic circuit. Speed control, function control of DC
motor for cassette tape recorder, tape deck, telephone

answering machine.

Features

• Wide operating voltage range :1.8 to 8V.

• Has a logic circuit which operates in such a manner as
2 logic inputs cause FF, REW, GOVERNOR, BRAKE
mode to occur.

• Easy to vary speed at the GOVERNOR mode.

• Turning OFF the strobe pin cause little ICC to flow
(100µA).

• Large starting torque.
