The SI8445BA-C-IS1 with Digital Isolators 1 kV 4-channel digital isolator is a multi-channel digital isolation product manufactured by Silicon Labs. It is a 4-channel digital isolator that is rated for isolation voltage up to 1 kV and provides galvanic isolation between two channels. It offers bidirectional communication protocol support, low propagation delay, wide input/output range, and low power consumption. This isolator is optimized for power system applications such as motor drives, motion control, power inverters, and AC line protection. It is capable of supporting up to 6 Mbps data rates, allowing it to significantly reduce system latency. With its programmable I/O rise and fall times, this device offers improved signal integrity and immunity to noise, making it suitable for harsh EMI environments.
