General Description

The AM4953 is a single-phase BTL output fan motor

driver

designed

by

bipolar

process.

This

IC

features high efficiency, silent operation and includes

lock shutdown and automatic restart functions. When

the

motor

is

under

lock

condition,

the

lock

shutdown function turns off the output current. When

the

lock condition

is

removed,

the

IC

will

restart automatically and allow DC fan to run. It is

applied for high reliability and low noise application,

such as personal computers, notebook, car audio,

CPU

cooling

systems

and

power

supplies

in

consumer electronics systems.

The AM4953 is available in MSOP-10, SSOP-10,

MSOP-8, SOIC-8 and PSOP-8 packages.
