3 Description
The DRV2901 is a high performance lens cleaner
transducer driver. This system only requires a
simple passive LC demodulation filter to deliver highquality,
high-efficiency amplification with proven EMI
compliance. This device requires two power supplies,
at 12 V for GVDD and VDD, and 12 V to 48 V
for PVDD. The DRV2901 does not require power-up
sequencing due to internal power-on reset.
The DRV2901 has an innovative protection system
integrated on-chip, safeguarding the device against a
wide range of fault conditions that could 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.
