AW86907-Q1 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 AW86907-Q1 an ideal haptic driver for fast responses.
AW86907-Q1 integrates a 12KByte 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.
AW86907-Q1 integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms(short ｏｒ long) on different LRA motor.
AW86907-Q1 supports LRA fault diagnostic based on resistance measurement ａｎｄ protections of short-circuit, over-temperature ａｎｄ under-voltage.
AW86907-Q1 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.
AW86907-Q1 features configurable automatically switch to standby mode. This can less quiescent power consumption. Dedicated interrupt output pin can detect real time FIFO status ａｎｄ the error status of the chip.
AW86907-Q1 features general settings are communicated via an I2C-bus interface ａｎｄ its I2C address is configurable.
AW86907-Q1 is available ｉｎ a WBQFN 4mmX4mmX0.75mm-32L package.
