AW8623 Low Power F0 Detect and Tracking LRA/ERM Haptic Driver

AW8623 is a single chip, low cost H-bridge haptic driver IC that integrates configurable overdrive and brake function, up to 8KB waveform memory, and supports real time playback, memory playback and hardware trigger playback with fast startup time. All these make it an ideal candidate for haptic driver.The internal F0 detect function can trace the actual F0 frequency after LRA delivered to customs or after LRA mounted in the mobile, which can keep a strong vibration under all circumstances.The software configurable automatic overdrive process incorporating with the internal waveform memory and a variety of playback modes makes the control of complex haptic effects economical, simple and flexible.AW8623 supplies Short Circuit Protection, Over-Temperature Protection and Under-Voltage Protection for robust operation.AW8623 features configurable automatically switch to standby mode to help reduce power consumption. The RSTN pin provides further power saving by fully shut down the whole device. The dedicated interrupt output pin can detect realtime FIFO status and the error status of the chip.
