MAX1749：SOT23 Vibrator Motor Driver
Allows Constant Vibration Force over the Battery Voltage Range
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 remail 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.
