Power chip

The LC898302AXA is an LRA (Linear Resonant Actuator) and ERM (Eccentric Rotating Mass) driver IC designed for haptic feedback drivers and vibrators employed in mobile devices. Thanks to the product's superior technology, the driver frequency can be automatically adjusted to the resonant frequency of the linear vibrator without using other external parts. By using this very energy-efficient drive, powerful vibrations can be achieved using very little energy compared to conventional solutions. The drive and brake are fully configurable via PWM-IF settings. Finally, raw drive waveforms can be used to reduce power consumption, which helps preserve battery life.
