AW86927G 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 AW86927G an ideal haptic driver for fast responses.
AW86927G 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.
AW86927G integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms(short or long) on different LRA motors.
AW86927G supports LRA fault diagnostic based on resistance measurement and protections of short-circuit, over-temperature and under-voltage.
AW86927G 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.
AW86927G 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.
AW86927G features general settings are communicated via an I2C-bus interface and its I2C address is configurable.
AW86927G is available in a FCQFN 2mm x 3mm x 0.55mm -20L package.
