LC898302AXA-MH ON Semiconductor

LC898302AXA Advance Information CMOS LSI Linear Vibrator Driver www.onsemi.com 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 WLCSP6, 0.78x1.18 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. Features 1) Automatic adjustment to the resonance frequency for LRA 2) Automatic braking (EN mode only) 3) Adjustable Drive voltage through PWM-IF setting 4) Adjustable Brake voltage through PWM-IF setting 5) EN/PWM-IF driving mode available by automatic detection 6) low standby current 7) Low power consumption thanks to the highly effective drive 8) Low driving noise (EMI, Audible band) 9) Thermal shutdown protection 10) Available to drive a LRA or ERM. 11) VBAT compliant Applications 1) Mobile Phone 2) Portable Game 3) Mobile equipment with haptics function This document contains information on a new product.
