Unlock the High-Definition Haptics Revolution
CapDriveTM technology is the name of our scalable high-voltage driver architecture. It has been designed from the ground up specially for piezoelectric actuators. The ultimate goal was to offer the best performance and the lowest power consumption to unlock the full potential of piezo actuators.
The BOS1901 single-chip piezo actuator is our first product based on the CapDriveTM. Its performance and ultra-low-power consumption makes it perfect for applications where power and space is limited like:
Smartphones and Tablets
Keyboards and Mice
Up to 20 Times More Power Efficient
Our piezo driver is in a league of its own and can be up to 20 times more efficient depending on the application.
Less power consumption also means less heat dissipation. Forget overheating problems.
Perfect for power and space limited devices like smartphones and wearables.
Power Consumption of Different Haptic Technologies - Normalized to LRA
Piezo - Boréas
Piezo - Leading Solution
Data extracted from Haptic Energy Consumption, Application Report SLOA194, Texas Instruments (TI), May 2014. Data point for Boréas was extrapolated from comparative measurements between the TI DRV8662 chip and Boréas’ driver.
Thanks to the piezoelectric reversible effect, a piezo actuator under pressure can send an electric charge and be used as a pressure sensor.
Until now, you needed another integrated circuit to sense the pressure next to the driver. The BOS1901 is the first ultra-low-power piezo driver that can do both.
Save space and reduce your bill of material.
Industry's Smallest Footprint
Coupled with our driver, the total space used by your haptic solution will be smaller than any comparable legacy technology.
Piezoelectric actuators size can be adapted to fit the size of your device.
Only 7 passive discrete components are required with our BOS1901 driver for a total of 115 mm2 area.
Fastest Response Time
Typical start-up time of less than 300 µs makes the BOS1901 latency insignificant in most systems.
Perfect for applications that need real-time haptic interactions like electronic gaming, mechanical button replacement and high-definition feedback.
