MM1426

MITSUMI Driver IC for Vibrators MM1426 Driver IC for Vibrators Monolithic IC MM1426 Outline This IC was developed as a driver for vibrator motors, and has an output voltage set at 1.3V. The input voltage is monitored, and if a constant voltage is not input the output is turned off. Features 1. Compact package for small mounting area. 2. In addition to output control through the input voltage, the IC can be turned on and off through the CONT pin. 3. Good ripple rejection. 4. Output currents of up to 150mA. 5. Operating voltage of up to 12V. 6. Output voltage is available in 0.1V steps from 1.2V to 2.0V.
