触觉驱动器用于ERM和LRA与内部存储器和智能环路架构 Haptic Driver for ERM and LRA with Internal Memory and Smart Loop Architecture
DESCRIPON
The DRV2604 is designed to give extremely flexible haptic control of ERM and LRA actuators over a shared I2C compatible bus. This relieves the host processor from ever generating pulse-width modulated PWM drive signals, saving both costly timer interrupts and hardware pins.
