IC for DC Motor Control MM1038

Outline

This IC is used to control the revolution rate of motors which can be controlled by low voltages. It can be

used to configure a high-precision FG motor using few external components. In particular, a unique new

circuit design with improved low-voltage operating characteristics enables configuration of sets such as

headphone stereos with auto-reverse functions which are unaffected by power supply voltage drops when the

motor is reversed, making them ideal for speed control of low-voltage DC motors.

Features

1. Operation at low voltages possible

2. Broad power supply voltage range

3. Small input current

4. Few external components, small package

5. Speed is easily changed over a wide range; accommodates two-speed operation
