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.
