GENERAL DESCRIPTION
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. 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. The AM9800 is available in SSOP-16 package.FEATURES
