Document Summary

The SIH6889C is a 20-pin high-voltage haptic driver IC. This chip supports low-power standby mode, real-time playback mode, stored playback mode, continuous mode, and test mode (including LRA resistance (RL) detection, LRA diagnostics, and VBAT measurement). Automatic braking is enabled in all playback modes. It includes a fast mode and an I2C interface.

The SIH6889C aims to provide advanced haptic experiences and perfect touch for smartphones, tablets, and wearable devices. It supports I2S functionality for better synchronization between haptic feedback, audio, and video playback. It supports unipolar PWM output drive. It supports OTP/OCP/UVLO/POR protection functions. It supports transmitting chip warnings and FIFO status via hardware pin interrupts. It supports automatic switching to standby mode after playback completion, and power-saving shutdown via hardware reset pin or software reset. It supports dual LRA synchronization via a single IIC bus. It also supports dual-chip synchronization via hardware pins.

The SIH6889C is packaged in a WLCSP package, measuring 1.75mm × 2.456mm × 0.555mm, with 20 pins.
