BTL Drive Single-phase Full-wave Fan Motor Driver
AM4953
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.
Features

Drive (Gain Resistor=1k to 360kΩ, Gain=51dB)
• Support Low-voltage Drive and Feature a Wide
Usable Voltage Range (2.2V to 16V)
• Low Saturation Output (High Side and Low Side
Saturation Voltage): VSAT_TOTAL=1.2V (typical,
IOUT=300mA)
• Built-in Lock Protection and Automatic Restart
Circuits
• Built-in FG/RD Output
• Built-in Hall Sensor Bias (VHB=1.45V)
• Thermal Protection Circuit
• Small-sized, High Thermal Capacity Package
Applications
• Notebook, Personal Computers
• Power Supplies in Consumer Electronics, Car
Audio
• CPU Cooling Systems

Note 1: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to “Absolute
Maximum Ratings” for extended periods may affect device reliability.
