General Description
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.
The output voltage can be adjusted from +1.25V to V
IN
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.
