Silicon IP builds cost-effective option for over-voltage in battery powered SoCs
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:
|
|
OPM-Angel |
RAR-OPM-Angel |
|
Optimisation |
low-area |
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] |
|
|
Availability |
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.
