Описание

The DRV2604L device is a low-voltage haptic driver that provides a closed-loop actuator-control system for high-quality tactile feedback for ERM and LRA. This schema helps improve actuator performance in terms of acceleration consistency, start time, and brake time and is accessible through a shared I2C compatible bus or PWM input signal. The DRV2604L device includes enough integrated RAM to allow the user to pre-load over 100 customized smart-loop architecture waveforms. These waveforms can be instantly played back through I2C or optionally triggered through a hardware trigger terminal. Additionally, the real-time playback mode allows the host processor to bypass the memory playback engine and play waveforms directly from the host through I2C. The smart-loop architecture inside the DRV2604L device allows simple auto-resonant drive for the LRA as well as feedback-optimized ERM drive allowing for automatic overdrive and braking. The smart-loop architecture creates a simplified input waveform interface as well as reliable motor control and consistent motor performance. The DRV2604L device also features automatic transition to an open-loop system in the event that an LRA actuator is not generating a valid back-EMF voltage. When the LRA generates a valid back-EMF voltage, the DRV2604L device automatically synchronizes with the LRA. The DRV2604L also allows for open-loop driving through the use of internally-generated PWM.
