DRV2605LYZFT

TEXAS INSTRUMENTS  DRV2605LYZFT  芯片, 触觉驱动器, 用于LRA/ERM, DSBGA-9

The is a low-voltage Haptic Driver which includes a haptic-effect library and provides a closed-loop actuator-control system for high-quality haptic feedback for ERM and LRA. The device offers a licensed version of TouchSense 2200 software from Immersion which eliminates the need to design haptic waveforms because the software includes over 100 licensed effects 6 ERM libraries and 1 LRA library and audio- to-vibe features. The DRV2605L 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 DRV2605L device automatically synchronizes with the LRA. The DRV2605L also allows for open-loop driving through the use of internally-generated PWM.
