AW8693X 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, auto dynamic sine playback, memory playback, cont playback, one wire playback, I2S/TDM playback and hardware pin trigged playback. A typical startup time of 1ms makes the AW8693X an ideal haptic driver for fast responses.
AW8693X integrates a 8KByte SRAM for user-defined waveforms to achieve a variety of vibration experiences, supporting 4 sampling rate(8k/12k/24k/48k) of waveforms loaded in SRAM, supporting output waveform sampling rate up-sampling to 48k.
AW8693X integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms(short or long) on different LRA motors.
AW8693X supports LRA fault diagnostic based on resistance measurement and protections of short-circuit, over-temperature and under-voltage.
AW8693X 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.
AW8693X 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.
AW8693X features general settings are communicated via an I2C-bus interface and its I2C address is configurable.
