TM6604 是天微电子专为驱动线性振动马达(LRA)开发的触觉反馈驱动器。
产品特色：
• 灵活触控反馈 -线性振动马达驱动(LRA)
• 针对LRA的自动谐振跟踪
• 无需频率校准
• 自动驱动换向
• 自动制动算法
• 宽输入脉宽调制(PWM)频率范围
• 自动输入电平转换
• 0%到 100%占空比控制范围
• 2.7V至 5.2V的宽电源电压范围
• 1.8V兼容，5V容限数字引脚
• 封装形式：SOT23-6、DFN6LE
应用领域：移动电话、平板电脑、动感游戏设备
TM6604 为具有低延迟、极高的效率、以及大驱动强度的便携式器件中线性马达(LRA)提供驱动控制。LRA驱动器通常有一个窄频带，在该频带内TM6604有充分的触觉反馈响应。
横向线性马达可以沿X与Y轴振动，马达振动行程更长，启动速度更快，振动方向可控。超细腻的快速响应振动反馈，TM6604通过对共振载波振幅进行调制，振动频率与振幅控制，可以产生各种不同的触觉反馈效果，形成复杂的振动，弹簧+磁铁的组合可以显著降低功耗。
