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.
Package
SOT-25A
Applications
Cellular phones, PHS, game, pagers.

Voltage-supply input pin
Output voltage is not output when input voltage
is less than input voltage detection value.
Note that consumption current flows even
when output voltage is OFF due to input
voltage detection. Turn output OFF with the
CONT pin in order to suppress consumption
current completely.
