BCD Semiconductor Manufacturing Limited AM4951R
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.| Part No. | AM4951R |

GENERAL DESCRIPTION
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
