DESCRIPTION
The ZCC1923 is a single-chip piezo actuator driver with energy recovery, based on Analogwin’s patented technology. It can drive actuators with waveforms up to 190 Vpk-pk while operating from a 2.3 to 5.5 V supply voltage. Its low power and small size make it ideal for a variety of applications requiring minimal power consumption. The CC1923 features high-resolution piezo sensing capabilities allowing haptic feedback to be automatically played when detection conditions are met.
The ZCC1923 differential driver achieves low distortion waveforms and quiet actuator operation. All settings are adjustable through the digital front end to reduce the BOM. Data and configuration parameters are easily communicated to the ZCC1923 through its two wire I2C interface. A flexible deep FIFO enables the streaming of digital waveform data for playback or the transmission of burst data for more bandwidth efficiency. The CC1923 also integrates 1.5 kB of RAM waveform memory to generate HD haptic waveforms with minimal communication bandwidth.
A dedicated SYNC pin can synchronize multiple ZCC1923 controllers to simultaneously drive multiple actuators within 2µs.
In addition to SYNC synchronization, ZCC1923 can also support CLK_SYNC synchronization. This function synchronizes the clock CLK, and multiple chips share the same CLK.
With a typical start-up time of less than 200µs, the CC1923 latency is negligible in most systems.
Various safety systems protect the ZCC1923 from damage in case of a fault.
