General Description The CA-IS3541 is high-performance, low-power fourchannel digital isolators specially developed for smart electricity meters (IR46). This family of devices features up to ±10k V surge tolerant and ±8k V HBM ESD protection. The digital isolator is based on Chipanalog’s advanced isolation architecture with up to ±5k VRMS isolation rating and ±150k V/μs CMTI, that provides a robust isolated data path between the different power domain and requires no special considerations or initialization at start-up. A simplified block diagram for a single CA-IS3541 channel is shown in the figure below. The CA-IS3541 has 3 forward and 1 reverse-direction channels. All of devices in this family e with enable control pins which can be used to put the driver outputs in high-impedance for...
