AW86223A/B 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, PWM, and hardware pin trigged playback with fast start up time. All these make the AW86223A/B an ideal candidate for haptic driver.
AW86223A/B 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.
AW86223A/B integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms (short in long) on different LRA motors.
AW86223A/B supports LRA fault diagnostic based on resistance measurement and protections of short-circuit, over-temperature and under-voltage.
AW86223A/B 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. Dedicated interrupt output pin can detect real time FIFO status and the error status of the chip.
AW86223A/B features general settings are communicated via an I2C-bus interface.
AW86223A/B is available in a QFN 2mmX2mmX0.5mm-12L package.
