描述 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.
AW86225 features general settings are communicated via an I2C-bus interface.
AW86225 is available in a WLCSP 1.127mmX1.127mmX0.557mm-9B package.
