AW86927 is a high voltage H-bridge, single chip LRA haptic driver, with F0 detecting ａｎｄ tracking based on BEMF, with a boost converter up to 11V drive voltage inside, supporting real time playback, memory playback, cont playback, one wire ａｎｄ hardware pin trigged playback. A typical startup time of 1ms makes the AW86927 an ideal haptic driver for fast responses.
AW86927 integrates a 8KByte 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.
AW86927 integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms(short ｏｒ long) on different LRA motors.
AW86927 supports LRA fault diagnostic based on resistance measurement ａｎｄ protections of short-circuit, over-temperature ａｎｄ under-voltage.
AW86927 integrates a high-efficiency boost converter as the H-Bridge driver supply rail. The output voltage, maximum current limit ａｎｄ maximum boost current are configurable.
AW86927 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.
AW86927 features general settings are communicated via an I2C-bus interface ａｎｄ its I2C address is configurable.
AW86927 is available ｉｎ a FCQFN 2mm x 3mm x 0.55mm -20L package.
