AW86907 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 an ideal haptic driver for fast responses.
AW86907 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 integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms(short or long) on different LRA motor.
AW86907 supports LRA fault diagnostic based on resistance measurement and protections of short-circuit, over-temperature and under-voltage.
AW86907 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 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 features general settings are communicated via an I2C-bus interface and its I2C address is configurable.
AW86907 is available in a FCQFN 2mm x 3mm x 0.55mm -20L package.
