FAH4820 - Fairchild Semiconductor

FAH4820 Direct Driver

The FAH4820 is a high-performance enhanced ERM driver for mobile phone and other hand-held devices. This device does not require a PWM signal to generate vibration of the ERM; it is controlled by the drive level on the HEN input. The ERM spins for the length of time that the HEN pin is held HIGH, then stop when the HEN pin is pulled LOW. The FAH4820’s regist.
