Applications • • • • • 3. I2C, SMBus, PMBus™ Interfaces Motor control systems Medical Equipment Battery Management Instrumentation General Description The CA-IS302x devices are complete dual-channel, galvanic digital isolators with up to 3.75kVRMS (narrow-body package)/5kVRMS (wide-body package) isolation rating and Copyright © 2020, Chipanalog Incorporated Shanghai Chipanalog Microelectronics Co., Ltd. ±150kV/μs typical CMTI. All device versions have Schmitt trigger inputs for high noise immunity and each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier to provide high electromagnetic immunity and low EMI. These devices feature high-integration design and only require fewer external components, VDDA, VDDB bypass capacitors and pull-up resistors, to build an isolated I2C interface. This family of devices operates from DC to 2.0MHz. The CA-IS3020 offers two bidirectional, open-drain channels for applications, such as multi-master I2C, that require data and clock to be transmitted in both directions on the same line. The CA-IS3021 provides an isolated I2C compatible interface supporting master mode only, with a unidirectional clock (SCL), and bidirectional data (SDA). All devices feature independent 3.0V to 5.5V supplies on each side of the isolator and the logic levels are set independently on either side by VDDA and VDDB. A simplified block diagram for a single CA-IS302x bidirectional channel is shown in the figure below. The CA-IS302x series of devices are specified over -40°C to +125°C operating temperature range and are available in 8-pin SOIC narrow body package, 8-pin SOIC wide body package and 16-pin SOIC wide body package. The wide temperature range and high isolation voltage make the devices ideal for use in harsh industrial environments.
