ICs for Motor
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.
s Features
• Wide operating supply voltage range ; V_CC =4.5V to
14V
• Stable reference voltage (1.3V) and easy speed control
• Large starting torque and maximum control torque
• Good secular drift because of external power transistor
• Provided with the motor stop function ; I_CC =20µA or
less at stop time
• Capable of controlling forward/reverse rotation, fast for-
ward/constant speed, and start/stop via 3 input pins
s Applications
• Speed control of the micromotors for the radio cas-
settes
• Speed control of the micromotors for the microcas-
settes of the automatic answering telephone sets
• Control of the tape loading motors for the DATs, etc.
