CapDriveTM Technology

most efficient piezo driver

Up to 20 Times More Efficient

Piezoelectric haptic solutions become the most efficient technology with our BOS1901 piezo driver and CapDrive™ technology.

Ideal for applications where power and heat dissipation are limited.

only piezo driver with integrated sensing

Integrated Piezo-Sensing

The BOS1901, with CapDrive™ technology, is the only ultra-low-power piezo driver to be able to sense and actuate from the same actuator.

Save some board space and reduce your BOM.

piezo driver industry smallest footprint

Industry's Smallest Footprint

With only seven external components required and its QFN20 4x4x0.8 mm size, the BOS1901 piezo driver has the smallest footprint in the industry.
