Data Sheet
BTL Drive Single-phase Full-wave Fan Motor Driver
AM4951/R/2
General Description
The AM4951/R/2 series 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 AM4951/R series is available in MSOP-8 (12V
application only) or PSOP-8 (24V application only)
package. The AM4952 is available in MSOP-10
package.
Features
• BTL Output Single-phase Full-wave Linear
Drive (Gain Resistor=1k to 360k, Gain=51dB)
• Support Low-voltage Drive and Feature a Wide
Usable Voltage Range (2.2V to 24V)
• Low Saturation Output (High Side and Low Side
Saturation Voltage): VSAT_TOTAL=1.2V (typical,
IOUT=200mA)
• Built-in Lock Protection and Automatic Restart
Circuits
• Built-in FG/RD Output
• Built-in Hall Sensor Bias (AM4952 Only,
VHB=1.5V)
• Thermal Protection Circuit
