Description
The AM9800 is a direct PWM driver IC designed for three-phase brushless motors. Also, by using highly silent PWM drive, switching current of the phase with a smooth slope reduces the sound of slewing motor, and makes high-efficiency drive a reality by a synchronous commutation. The device is build-in lock protection. When the fan is locked, the device will enter the lockup protection mode. It is also equipped with thermal shutdown function and forward or reverse rotation selection. In normal operation, supply current is less than 2mA, but in PWM=0 mode it is just around 20μA.
