A1448
Description (continued)
portable electronic devices. This feature allows the removal of a
FET transistor for switching the device on and off.
The A1448 is optimized for vibration motor applications in cel-
lular phones, pagers, electronic toothbrushes, hand-held video
game controllers, and can also be used as a micro-fan driver for
fans motors up to 1 W.
The Allegro DFN (EW) package is the thinnest DFN in the

industry with a 0.40 mm maximum thickness that allows for very
thin BLDC coin motor designs. The small package outline and
low profile make this device ideally suited for use in applications
where printed circuit board area and component headroom are at
a premium. It is available in a lead (Pb) free, 6-contact MLP/DFN
micro-leadframe package, with an exposed pad for enhanced
thermal dissipation. Leadframe is 100% matte tin plated.
