Dolphin Design offer a Reusable Power Kit Library 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 3.3 V devices.
The OPM-Angel-AR is optimized to be used for retention mode in low power applications.
Over-voltage Protection Module to handle Over-voltage operation (up to 5.5 V) while using standard process 3.3 V devices
Overview
Key Features
- Over-voltage protection biasing for embedded regulators
- Avoids expensive solutions while enabling direct baterry connection.
- Built-in over-voltage protection (up to 5.5 V) using 3.3 V transistors
- Over-voltage power range: 1.9 V to 5.5 V
- Fixed 2.6 V regulated output voltage with 10% accuracy
- Low-leakage for SoC retention mode
- Low power mode quiescent current (at ILOAD = 0 mA): 400 nA
- Low noise enhancement: improve the network PSRR up to 40 dB when input supply is higher than 2.8 V
- Behavioral models: ease of integration in SoC and optimization of Power Management Network (PMNet) using models to verify mode transitions as well as noise propagation
