AW8624 is a single chip, low cost H-bridge haptic driver IC that integrates configurable automatic overdrive and brake function, up to 8KB waveform memory, and supports real time playback, memory playback and hardware triggered 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 and brake process incorporating with the internal waveform memory and a variety of playback modes makes the control of complex haptic effects economical, simple and flexible.
AW8624 supplies Short Circuit Protection, Over-Temperature Protection and Under-Voltage Protection for robust operation.
AW8624 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 real time FIFO status and the error status of the chip.
The AW8624 is available in WLCSP 1.369X1.369-9B package.
