General Description
AW86225 is a low cost H-bridge, single chip LRA
haptic driver, with F0 detecting and tracking based
on BEMF, supporting real time playback, memory
playback, Cont playback and hardware pin trigged
playback with fast start up time. All these make the
AW86225 an ideal candidate for haptic driver.
AW86225 integrates a 3KByte SRAM for user-
defined waveforms to achieve a variety of
vibration experiences, supporting 3 sampling
rate(12k/24k/48k) of waveforms loaded in SRAM,
supporting output waveform sampling rate up-
sampling to 48k.
AW86225 integrates an autobrake engine to
suppress the aftershocks to zero for different drive
waveforms (short or long) on different LRA
motors.
AW86225 supports LRA fault diagnostic based on
resistance measurement and protections of short-
circuit, over-temperature and under-voltage.
AW86225 features configurable automatically
switch to standby mode after haptic waveform
playback finished. This can less quiescent power
consumption. The RSTN pin provides further
power saving by fully shut down the whole device.
Reused interrupt output pin can detect real time
FIFO status and the error status of the chip.

communicated via an I2C-bus interface.
