Haptic driver for ERM/LRA with 2-V operation, waveform memory & auto-resonance tracking

DRV2604LYZFR General Description

The DRV2604L haptic driver is a versatile solution for improving tactile feedback in devices. By providing a closed-loop actuator-control system, it ensures high-quality performance for ERM and LRA technologies. Users can easily access and control the driver through a shared I2C compatible bus or PWM input signal, enhancing the overall actuator acceleration consistency, start time, and brake time
