Dolphin Integration reveal a cost effective solution to handle over-voltage operation in battery powered SoCs
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 thus lead Fabless companies to use expensive alternatives, such as external regulators or expensive process options, including HV/BCD processes. Today, Dolphin Integration propose …
