Overview

The TS_OVLO_3V3_X8 protects battery-operated circuits against damage when they are exposed to risks of their supply connector accidentally being wired to higher or wrong-polarity voltages, with extremes at ±30V. When battery-side input VBAT receives a voltage outside the range from 0V to typically +3.53V, the OVLO breaks the current paths to the three outputs VOUT1, VOUT2 and VOUT3.

When VBAT voltage is valid, the TS_OVLO_3V3_X8 draws as little current as 950nA maximum over the air temperature range from -40°C up to +85°C, which is ideal for battery longevity during shutdown periods. The on-state resistance to outputs VOUT2 and VOUT3 is 65Ω maximum for low battery voltage at +2.1V. The on-state resistance to output VOUT1 is 3Ω maximum and it can be further reduced by placing external PMOS switches in parallel, of which the gate is driven by control output PGATEOV.

The TS_OVLO_3V3_X8 contains a multiplexer that switches output VOUT1 over to system-side power input VIN2 when control input ONVIN2 is pulled up and provided that its voltage is regulated to 3.3V±0.1V. The corresponding on-state resistance is 1Ω maximum over the junction temperature range from -40°C up to +150°C.

The minimum continuous operation lifetime spans 100000 hours.

A versatile Control Network of power domains in a low power SoC

Developing and verifying a control network in a low-power SoC is a challenging task, especially managing the different states of regulators and modes of power domains. This article first describes state-of-the-art approaches to addressing this issue, and then delves into the solution promoted by Dolphin Integration to go further, thanks to the easy and secure Maestro� solution to manage SoC power mode transitions.

An ESD efficient, Generic Low Power Wake up methodology in an SOC

As the semiconductor industry is moving towards lower technology nodes, more and more complexity is being introduced in the design to beat the competition and provide most innovative solution to cater the needs. One of the biggest challenges that the designer faces is in terms of the keeping the power budgets of the chip within the specification and even innovate to reduce the current numbers. Depending on the application requirements, the designers have to tune up the power profile of the SoC. There are various ways to do so like dynamically changing frequency and voltage of operation, considering system level contributions to power consumption, using various modes of operation etc. In most of the cases, SoC has to support various power modes like Run mode, Sleep mode, Halt mode etc. Different power numbers are defined for each mode. Run modes can further be divided in various sub modes depending on application.

D32PRO, scalable & royalty free 32-bit CPU

D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.
