TDA1154
SPEED REGULATOR FOR DC MOTORS
MATCHING FLEXIBILITY TO MOTORS WITH
VARIOUS CHARACTERISTICS
BUILT-IN CURRENT LIMIT
ON-CHIP 1.2V REFERENCE VOLTAGE
STARTING CURRENT: 0.5 A @ 2.5V
REFLECTION COEFFICIENT K = 20
DESCRIPTION
The TDA1154 is a monolithic integrated circuit in-
tended for speed regulation of permanent magnet
dc motors used in record players, tape recorders,
cassette recorders and toys.
The circuit offers an excellent speed regulation with
much higher power supply, temperature and load
variations than conventional circuits built around
discrete components.
