Chipanalog Micro CA-IS3621

Description

The CA-IS362x is a chip in the digital isolator series with reinforced isolation withstand voltage and integrated DC-DC converter. The emergence of the CA-IS362x can replace the traditional isolated power supply scheme built with discrete devices, and the new scheme makes the form factor smaller and can achieve complete isolation. The CA-IS3620/CA-IS3621/CA-IS3622 are dual-channel digital isolators.The CA-IS3620 chip has two channels in the same direction, and the CA-IS3621 and CA-IS3622 chips have one forward and one reverse channel. All devices have a fail-safe mode option that defaults to low output for chips suffixed with L and high for chips suffixed with H if the input signal is lost.
