Boreas Technologies' drives are suitable for applications where power consumption and heat dissipation must be minimized

     Boreas Technologies' BOS1901 is a single-chip piezoelectric actuator driven with energy recovery capabilities based on a patent-pending CapDrive technology. It can drive drivers up to 190 V(pk-pk) waveforms while operating at a supply voltage of 3 V to 5.5 V. The input digital stream is written inside the FIFO through the digital interface to generate the desired output waveform. The low power consumption and small size make it suitable for a variety of applications where power consumption and heat dissipation need to be minimized.

     BOS1901 uses a high-speed SPI on its digital front end. It enables devices to share the common communication bus of multi-actuator systems, and users can query various data, such as actuator voltage for sensing applications.Differential drivers achieve low distortion waveform and quiet actuator operation. All Settings are adjustable through the digital front end to reduce BOM. Only seven passive discrete components are required. BOS1901 can work with a variety of commercial off-the-shelf inductors.

     The BOS1901 has unidirectional power input (UPI) among systems that cannot handle reverse currents in a power transmission network. When UPI mode is activated, the driver performs a resistive load without reducing power efficiency. Typical boot times of less than 300 μs on most systems make BOS1901 lag irrelevant. Safety system protects equipment from damage in case of failure.
