SI8600AB-B-ISR-HXY

The SI8600AB-B-ISR is a low-power bidirectional isolator compatible with the I²C interface. These devices use a silicon dioxide isolation barrier to separate the logic input and output buffers, blocking high voltage and preventing noise currents from entering the control-side ground, thereby avoiding circuit interference and protecting sensitive components. Based on iDivider technology, the device offers advantages over optocouplers in functionality, performance, size, and power consumption. The SI8600AB-B-ISR provides two bidirectional channels supporting a complete isolated I²C interface, suitable for single-master applications. The device features independent 3.0V supplies on both sides of the isolator, operates over a frequency range from DC to 2MHz, supports an operating temperature range of -40°C to +125°C, and accepts supply/logic levels of 3.0V~5.5V.
