AN6657, AN6657S
Micromotor Forward/ Reverse Electronic Governors
s
Overview
The AN6657 and the AN6657S are the electronic gov-
ernors capable of controlling the forward/reverse speed,
fast forward, rewind, and start/stop of the micromotors
used for the radio/cassette tape recorders, automatic an-
swering telephone sets, and so on.
