Description

AW86256 is a low cost H-bridge, single chip LRA haptic driver, with F0 detecting and tracking based on BEMF, supporting real time playback, memory playback, Cont playback, I2S/TDM playback ,and hardware pin trigged playback with fast start up time. All these make the AW86256 an ideal candidate for haptic driver. AW86256 integrates a 4KByte 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. AW86256 integrates an autobrake engine to suppress the aftershocks to zero for different drive waveforms (short or long) on different LRA motors. AW86256 supports LRA fault diagnostic based on resistance measurement and protections of short-circuit, over-temperature and under-voltage. AW86256 features configurable automatically switch to standby mode after haptic waveform playback finished. This can decrease quiescent power consumption. Interrupt output pin can detect real time FIFO status and the error status of the chip. AW86256 features general settings are communicated via an I2C-bus interface.

Hardware development

Evaluation board

AW8625XQNR_EVB_DB_V1.0 — The demonstration board of Aiwei linear motor is composed of bottom board HAPTIC EVB and AW8625X small board. HAPTIC EVB V4.0 is the motherboard of the fourth generation demonstration board of Aiwei linear motor. With AW8625X_EVB_DB_V1.0 small board, the demonstration of driving linear motor can be realized. Demo board with supporting software can demonstrate the driving applications of linear motors such as RAM mode, RTP mode, TRIG mode, CONT mode and Tiktap Engine mode. AW8625X series includes AW86253QNR, AW86253AQNR, AW86254CSR, AW86254ACSR, AW86255ACSR, AW862555ACSR, AW86256QNR and AW86256AQNR.
