Description
BTL Drive Single-phase Full-wave Fan Motor Driver
Manufacturer
BCDSEMI [BCD Semiconductor Manufacturing Limited]
Datasheet
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
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.
