Bor é as BOS1921 meets the requirements of ultra-thin PC touch panel for high-performance and low-cost tactile functions

Time:2022-10-05 Views:1673
    Piezoelectric tactile driver saves BOM cost and hardware space, while improving responsiveness and resolution
    Bor é as Technologies launched the miniature piezoelectric driver product BOS1921, which can provide the piezoelectric tactile touch panel with autonomous operation and sensing functions through a single chip. It is different from other piezoelectric drivers that need special force sensing electronic devices, which can save PC OEMs. Compared with Bor é as‘ first generation piezoelectric tactile driver BOS1901, BOS1921, which is more advanced, reduces the cost of bill of materials (BOM) by up to twice, reduces the thickness of piezoelectric tactile touch panel, improves the response capability, and provides 15 times higher sensing resolution.
   
     Simon Chaput, founder and CEO of Bor é as Technologies, said: "PC OEMs are in a market with fierce competition and low profits, and piezoelectric tactile touch panels have become an important differentiated component that stands out from the crowd. Compared with the old mechanical touch panels, piezoelectric touch panels are thinner and lighter, supporting a more crisp tactile experience; piezoelectric touch panels are increasingly adopted by the design of laptops and laptops. Our piezoelectric touch driver products, including BOS1921, are leading the industry Change. "


Main characteristics of BOS1921 piezoelectric actuator
Autonomous operation
    • Integrated digital front-end with 13C/I2C and Waveform Synthesizer (WFS), eliminating special electronic devices such as microcontrollers, thereby reducing BOM costs and saving circuit board space

High resolution voltage inductance measurement
    • 7 mV sensing resolution, interrupt generation and automatic trigger haptic feedback function, providing higher sensitivity and the lowest delay haptic feedback on the market, improving user experience

CapDrive technology
    • Power consumption is 10 times lower than that of competitive haptic platforms, extending battery life
    • Integrated sensing function to reduce BOM cost
Wide band wide high voltage output for driving multiple applications
    190 Vpk pk (+/- 95V) output voltage and 3V to 5.5V wide power supply voltage range support various piezoelectric actuators, providing design flexibility for PC touch panel, micro pump, piezoelectric fan and other applications
