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