AW86715 integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms(short in long) on different LRA motor.
AW86715 supports LRA fault diagnostic based on resistance measurement and protections of short-circuit, over-temperature and under-voltage.
AW86715 integrates a high-efficiency charge pump as the H-Bridge driver supply rail. The output voltage, maximum current limit and maximum charge pump current are configurable.
AW86715 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.
AW86715 features general settings are communicated via an I2C-bus interface and its I2C address is configurable.
AW86715 is available in a FCQFN 2mm × 2mm × 0.55mm -16L package.
