Boréas Technologies Inc. is a fabless semiconductor company commercializing product-differentiating integrated circuits for haptic applications in consumer and industrial markets. Boréas demoed the BOS1901, the lowest-power piezoelectric driver integrated circuit (IC) for high-definition (HD) haptic feedback in wearables and other battery-powered consumer devices at Display Week 2019. The BOS1901 is a single-chip piezo actuator driver with energy recovery, based on a patent pending CapDrive™ technology. It can drive actuators with up to 190 V waveforms while operating from a 3-5.5 V supply voltage. The input digital stream is written in the internal FIFO over the digital interface to generate the desired output waveform. Low power and small size make it suitable in a variety of applications where power consumption and heat dissipation must be minimized.
