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.
