Ultra-small Digital Isolators with Iso-power
The CA-IS2631HA integrated signal and power isolation device simplifies system design and reduces board area. This device is high-performance, triple-channel, unidirectional digital isolators with up to 2.5kVRMS isolation rating and ultra-fast data rate. The integrated isolated DCDC converter provides up to 500mW of isolated power and different output voltage configurations. Each isolation channel has a logic input and output buffer separated by capacitive silicon dioxide (SiO2) insulation barrier, the integrated Schmitt trigger on each input provide excellent noise immunity. With these advanced features, the CAIS2631HA digital isolator offers high electromagnetic immunity and low emissions while isolating different ground domains and block high-voltage/high-current transients from sensitive or human interface circuitry.
The CA-IS2631HA has 2 forward and 1 reverse-direction channels. It comes with enable control pin which can be used to put the driver output in high-impedance for the multi-master driving applications. The CA-IS2631HA also features different default outputs. When the input is either not powered or is open-circuit, the default output is high for driver output VO1/VO3 and low for driver output VO2.
The CA-IS2631HA is specified over the -40°C to +125°C operating temperature range and is available in LGA16 small package.
