Dolphin Design provides a complete Power Management IPs platform, toward three objectives:
To standardize and ease Power Regulation Network integration
To enable diverse optimizations
To reduce Time-to-Market
To avoid expensive solutions, such as additional mask layer or external regulators, the library features a cost effective alternative with a set of Over-voltage Protection Modules (OPM). These companions for regulators enable over-voltage operation while using standard process 1.8 V devices.
The OPM-Angel-AR-LP is optimized to be used for retention mode in low power applications.
Applicable to automotive, industrial.
Designed for extended mission profile (aging report available)
