FAH4820

Direct Driver for DC Motors (ERMs)

Description

Features

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 register maps are

accessible via I²C serial communication, which is useful

for higher or lower drive voltage across the ERM or if

disabling the device is desired.
