3 Overview

CA-IS36xx is a series of digital isolators that enhance isolation and withstand voltage and integrate

A chip of DC-DC converter. The emergence of CA-IS36xx can replace the traditional

The isolated power supply scheme is composed of discrete devices, and the new scheme makes the appearance

It is smaller and can achieve complete isolation.

CA-IS3620/CA-IS3621/CA-IS3622 is a dual-channel digital isolator.

CA-IS3640/CA-IS3641/CA-IS3642/CA-IS3643/CA-IS3644 Yes

Four-channel digital isolator.

CA-IS3620 chip has two channels in the same direction, and CA-IS3621 and CA IS3622 chip have two reverse channels, as shown in Figure 7-1. CA IS3640 chip has four forward channels, and CA-IS3641 chip has three

Two forward channels and one reverse channel, CA-IS3642 chip has two

Forward channel and two reverse channels, CA-IS3643 chip has one forward channel

The forward channel and three reverse channels, CA-IS3644 has four reverse channels,

As shown in Figure 7-2. All devices have fail-safe mode options, such as

If the input signal is lost, the default output of the chip with L suffix is low power

Flat, the default output of chips with H suffix is high level.
