LC898301XA中文资料Linear Vibrator Driver数据手册ONSEMI规格书

描述 Description

The LC898301XA is a Linear Vibrator 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 start time and brake time are fully configurable through the I2C setting. Moreover, an automatic braking function has been implemented allowing to optimize the braking time.
Finally, a self test mode allows to detect various possible functional defaults during assembly.

特性 Features

• Automatic adjustment to the resonance frequency for LRA (150Hz to 385Hz)
• Programmable or Automatic braking
• Initial drive frequency adjustment function
• Adjustable Drive voltage through I2C IF setting
• EN IF or PWM IF driving mode available by automatic detection
• Support various drive pattern through I2C (1.8V IF)
• Low power consumption thanks to the highly effective drive and the low power driving mode
• Low driving noise (EMI, Audible band)
• VBAT compliant
• Thermal shutdown protection
• Self test mode for defaults detection (open-circuit, short-circuit and weak back EMF)

应用 Application

• Linear Vibrator (Vibration and haptics)
• Mobile Phone
• Portable Game
• Mobile equipment with haptics function
