ICs for Motor
■ Overview
The AN6608, the AN6609N and the AN6609NS are the
electronic governors which incorporate the forward
/reverse rotation and double speed controls of the DC
motors used for radio/cassette tape recorder, and the
functions such as fast forward, rewind, brake, and pause.
They are also available for controlling the video tape deck
mechanisms such as the VCRs and DATs. The AN6608,
the AN6609N and the AN6609NS are identical with each
other except the operating logic by 3-bit input.
■ Features
•
Operating supply voltage range ; Vcc = 8V to 16V
•
Stable reference voltage (1.27V) and easy speed
adjustment
•
Large starting torque and maximum control torque
•
Built-in power transistor
•
Forward/reverse constant speed and double speed
controls, and fast forward, brake, and pause functions
available by 3-bit input
■ Applications
VCRs, cassette decks, radio/cassette tape recorders,
car cassette tape players, tape loading DC motor con
trol such as DATs.
