The DRV2901 is a high-performance lens cleaner transducer driver. This system only requires a simple passive LC demodulation filter to deliver high-quality, high-efficiency amplification with proven EMI compliance. This device requires two power supplies, at 12V for GVDD and VDD, and 12V to 48V for PVDD. The DRV2901 does not require power-up sequencing due to an internal power-on reset.

The DRV2901 has an remarkable protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that can damage the system. These safeguards are short-circuit protection, overcurrent protection, undervoltage protection, and overtemperature protection. The DRV2901 has a new proprietary current-limiting circuit that reduces the possibility of device shutdown during high-level transients.
