Piezo driver chip advances realistic haptic feedback in automotive HMIs
BOREAS TECHNOLOGIES BOS1211, the first low-power high-voltage piezoelectric driver integrated circuit (IC) enables high-definition (HD) haptic feedback in automotive human machine interfaces (HMIs), such as automotive infotainment screens and safety alerts in touch-sensitive steering wheels. Designed to support TDK Electronics’ family of 120V PowerHap piezo actuators —device is critical to satisfying growing demand for clear tactile feedback in automotive environments. Device is based on form’s patented CapDrive technology, a proprietary scalable piezo driver architecture that provides the foundation for its haptic chips. CapDrive delivers the advantages of piezoelectric material to the designer: greater energy efficiency, low heat dissipation and rapid response times, making CapDrive chips suitable for devices in which size, power, responsiveness and thermal management are essential.
