App note: Add a “Black Box” fault logger to your “Big (or Small) Box” system

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.

App note: Fundamentals of electronic security: Tampering with the easy targets

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 […]

App note: Passives aren’t really So Passive: PCB

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 […]

App note: Passives aren’t really So Passive: Resistors

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 […]

App note: Passives aren’t really So Passive: Capacitors

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, […]

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.

App note: Eliminate noise through proper supply bypass filtering

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.
