Application notes from Maxim Integrated on adding log functionalities in your system. Link here (PDF) This article describes how to add a “black box” functionality – nonvolatile fault logging – to networking, communications, industrial, and medical equipment. It outlines the benefits of recording fault data, including faster, more definitive failure analysis.
An app note from Maxim Integrated about tampering electronic securities through physical means and how to protect against it. Link here (PDF) More and more frequently, computer-based systems store valuable data and manage the flow of valuable commodities. If an opponent can gain control of the computer that touches this valuable data, they can access […]
The last part of “Passives aren’t really so passive” series app notes from Maxim Integrated discusses about PCB flaws that can lead to passive errors to IC performance. Link here (PDF) Active components like transistors and integrated circuits change signals using energy from the power supply. However, passive components like resistors, capacitors, inductors, and connectors […]
Part 2 of the “Passives aren’t really so passive” series app notes from Maxim Integrated, this time about resistors and their tempco and tolerance degeneration that need to be considered. Link here (PDF) Passive components don’t draw power but even resistors can, and modify signals in unexpected ways. A resistor’s reaction to temperature, voltage, and […]
Interesting app note from Maxim Integrated on small parasitic effects of capacitors that makes them less passive. Link here (PDF) Active components like transistors and integrated circuits change signals using energy from the power supply. Conversely, passive components like resistors, capacitors, inductors, and connectors do not consume power or so we like to assume. However, […]
Ever wonder why USB connector’s power are longer than the D+ D- pads? Here’s an app note from Maxim Integrated about these detection proccess and their importance. Link here (PDF) This application note explains details of the USB Battery Charging Specification 1.2, and the role of charger detection. With the use of charger detection ICs, […]
App note from Maxim Integrated on providing smooth power from two sources. Link here (PDF) Design provides a simple method for maintaining an uninterrupted +5V even while switching between the external +5V supply and a rechargeable single-cell Li+ battery.
Power supply filtering, an application note from Maxim Integrated. Link here If sensitive analog systems are run from one supply without the sufficient bypassing to eliminate noise, undesired degradation in a system’s performance will result. This application note provides insight into suitable techniques to overcome this roadblock.
Old app note from Maxim Integrated on DIY portable bluetooth audio system. Link (PDF!) here When people want portable music, they usually rely on battery-powered audio devices. With a bit of engineering blood (or curiosity) running in your veins, it is not difficult to build a wireless Bluetooth® stereo audio system that can be controlled […]
App note from MAXIM Integrated on LED lighting utilizing power from PoE. Link here This application note explains that Power-over-Ethernet (PoE) is a technology used in wired local area networks (LANs). PoE delivers power over the same cable that delivers the Ethernet data. Using LED lighting on a PoE network delivers excellent energy efficiency because […]
Here’s an app note from MAXIM integrated on using the time-to-digital converter chip MAX35101 for heat meters. Link is here Heating and cooling a living space is often the greatest contributor to energy consumption in both commercial and residential applications. It is for this reason that many conservation efforts focus on adding insulation and sealing […]
