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.
Automatic adjustment to the resonance frequency for LRA - Can ignore the deviation of resonance frequency thanks to Auto Tune function.
Automatic braking (EN mode only) - Can get crisp vibration thanks to Automatic braking and Automatic over driving.
EN/PWM-IF driving mode available by automatic detection - Controled by 1pin (PWM or EN)
Low power consumption thanks to the highly effective drive - Saving the battery life
Available to drive a LRA or ERM. - Saving the mounting space
Adjustable Drive voltage through PWM-IF setting
Adjustable Brake voltage through PWM-IF setting
low standby current
Low driving noise (EMI, Audible band)
Thermal shutdown protection
Haptics function units
Mobile equipment with haptics function
