DESCRIPTION
The CC1923 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 CC1923 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 CC1923 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
CC1923 controllers to simultaneously drive multiple
actuators within 2µs.
In addition to SYNC synchronization, CC1923 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 CC1923 from
damage in case of a fault
