5.5v over-voltage solution uses OPMs
Until now, portable devices supplied by USB, Li-ion or NiMH batteries with voltage levels up to 5.5 V could not use standard process devices, such as 3.3 V CMOS I/O transistors. This lead fabless semiconductor companies to use expensive alternatives, such as external regulators or expensive process options, including HV/BCD processes.
Dolphin Integration is proposing a cost effective alternative to such solutions with a set of Over-voltage Protection Modules (OPM). These OPM can be easily associated with embedded regulators and extend the benefit of their DELTA offering to enable:
- Over-voltage operation (up to 5.5 V) while using standard process devices, such as 3.3 V devices
- Direct connection to the battery with the capability to protect several regulators, leading to a decrease of the Bill-of-Materials
The components are part of Dolphin’s standardised offering for Power Management Networks: the DELTA Reduced Power Kit Library.
