SOT23 Vibrator Motor Driver

MAX1749

General Description

____________________________Features

♦ Fixed 1.25V or Adjustable (1.25V to 6.5V) Output

♦ Low Cost

The MAX1749 allows for a constant vibration force while

operating from a +2.5V to +6.5V input range and deliver-

ing up to 120mA. A PMOS pass transistor allows the

80µA supply current to remain independent of the load.

♦ Thermal Overload Protection

♦ Output Current Limit

The output voltage can be adjusted from +1.25V to V

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 avail-

able in a 5-pin SOT23 package.

♦ Reverse Battery Protection

♦ Low 0.1nA Off Supply Current

♦ Low 80µA Full-Load Supply Current
