Dolphin says it has a cost effective alternative to such solutions with a set of Over-voltage Protection Modules (OPMs). These OPMs can be 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-Material

Two OPMs, with and without a retention mode, are available to meet the main challenges facing fabless semiconductor companies:





low-leakage for SoC retention mode

Low power mode quiescent current (at ILOAD = 0 mA)

500 nA

Normal mode quiescent current

(at ILOAD = 0 mA)

15 μA

Area (180 nm)

0.27 mm2

0.59 mm2

Input Voltage Range configurations

[1.9 – 4.4 V] and [2.7 – 5.5 V]


From 180 nm down to 55 nm

These components are part of Dolphin’s standardised offering for power management networks: the DELTA Reduced Power Kit Library.
