MAX1749

19-1455; Rev 1; 6/99 SOT23 Vibrator Motor Driver General Description The MAX1749 allows for a constant vibration force while operating from a +2.5V to +6.5V input range and delivering up to 120mA. A PMOS pass transistor allows the 80µA supply current to remain independent of the load. The output voltage can be adjusted from +1.25V to VIN with an external resistor-divider. When turned off (ON = low), the MAX1749 supply current drops to 1µA (max) to minimize battery drain. Other features include short-circuit protection, thermal shutdown protection, and reverse battery protection. The MAX1749 is available in a 5-pin SOT23 package. ____________________________Features o Fixed 1.25V or Adjustable (1.25V to 6.5V) Output o Low Cost o Thermal Overload Protection o Output Current Limit o Reverse Battery Protection o Low 0.1nA Off Supply Current o Low 80µA Full-Load Supply Current MAX1749 ________________________Applications Wireless Handset Vibrator Motor Drivers Pager Vibrator Motor Drivers PART MAX1749EUK-T Ordering Information TEMP.
