Boréas Technologies BOS1211 CapDrive® Piezo Haptic Driver
Boréas Technologies BOS1211 CapDrive® Piezo Haptic Driver is a scalable piezo haptic controller based on patented CapDrive™ technology. This driver can drive TDK's PowerHap 120V piezo actuators or similar loads with up to 120V HD haptic low-distortion waveforms. The BOS1211 CapDrive® Piezo Haptic driver operates from a 12V supply voltage. The BOS1211 runs waveforms through its digital front-end and SPI interface. This Haptic driver features a piezo sensing interface that detects pressure applied to the piezo actuator, plays automatic haptic waveform feedback, and notifies the user. The BOS1211 CapDrive® Piezo Haptic driver is available in a wettable flank QFN-24 package. This CapDrive® driver is ideal for display haptics, button replacement, and human-machine interface.
