LC898302AXA中文资料Linear Vibrator Driver数据手册ONSEMI规格书

描述 Description

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.

特性 Features

• 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
• VBAT compliant

应用 Application

• Haptics function units
• Mobile Phone
• Portable Game
• Mobile equipment with haptics function
