Overview
LC898302AXA is a LRA (Linear Resonant Actuator) & ERM
(Eccentric Rotating Mass) Driver IC dedicated to haptic feedback
actuator and vibrator employed in mobile equipment. Due to the
product superior technology, the drive frequency is automatically
adjusted to the resonance frequency of the linear vibrator without the
use of other external parts. As a result of this very effective drive, the
vibration is as powerful as possible using very limited amount of
energy compared to classical solutions
The drive and brake are fully configurable through the PWM−IF
setting.
Finally, the original driving waveform allows you to reduce power
consumption and it is useful to maintain battery lifetime.
