Overview
The ADUM5402WCRWZ is a quad-channel digital isolator produced by Analog Devices Inc., featuring the integrated isoPower® DC-to-DC converter. This device leverages Analog Devices' iCoupler® technology to provide up to 500 mW of regulated, isolated power at 5.0 V. It eliminates the need for a separate isolated DC-to-DC converter in low-power, isolated designs. The iCoupler chip scale transformer technology ensures both logic signal isolation and the magnetic components of the DC-to-DC converter, resulting in a compact, total isolation solution. The device is qualified for automotive applications and offers high common-mode transient immunity and safety regulatory approvals such as UL recognition, CSA component acceptance, and VDE certificate of conformity.
