CBM has been one of the biggest challenges facing many companies in recent years. This is especially true in the industrial machinery industry, where replacement is difficult because of the large opportunity loss in the event of failure and the high unit price.
This time, we introduce IMV's vibration pickup sensor VP8021-A, which plays an important role in realizing CBM.

It is common to incorporate a mechanism in the circuit that monitors the power supply circuit and raises an alert when there is a system abnormality or power supply abnormality. It's good to monitor the power circuit, but it's very hard to see what kind of problem occurred on which power supply.
In such cases, it is very useful to be able to record the log when an error occurs. Now let's talk about logging solutions.

In the case of the power supply of the receiving electronics connected to the power supply terminal, in addition to the protection by current limitation due to the failure of the load circuit, protection of overvoltage due to ringing and surge generated when the cable is connected may be required. This can be easily accomplished using LT4363.

If the power supply is short-circuited due to a circuit failure or operation error, an overcurrent flows, which leads to a secondary failure of the power supply. In addition, heat generated from the circuit components can cause an accident such as a fire. For this reason, many power supplies have a protective function such as a current limiting function, but I think there are many cases where a fuse is inserted to improve reliability.
However, the fuse may be blown by the rush current when the power is turned on if the error of the blowing current is large and there is no margin. Also, once it has melted, it needs to be replaced, which makes maintenance troublesome.

In related article "Electronic circuit breaker with current detection amplifier" I introduced that breaker can be reset by turning on the power again or resetting by the LE terminal (temporarily set to low) after removing the fault. However, in the case of the master unit which supplies power to multiple slave units remotely, it may be difficult to set the reset terminal for each slave unit port or it may be convenient to automatically reset.
In such cases, it is useful to retry periodically and return automatically. This can be achieved with the additional circuit in LT6118, but it can be more easily achieved with LT1910.

Industrial ethernet must be more robust than standard office ethernet to ensure that certain data can be transmitted and received accurately, even in harsh industrial environments such as high temperatures, vibration, noise, and noise.
Analog Devices' industrial Ethernet PHY ADIN1200 and ADIN1300 provide more accurate and reliable industrial Ethernet communications.

A2B is an abbreviation for "Automotive Audio Bus". As the name suggests, it is a new technology developed with the aim of reducing the weight (fuel efficiency) and cost of audio harnesses used in in - vehicle infotainment systems, which are becoming increasingly popular. In addition to Ford Motor Co. of the United States, several other manufacturers in Japan, the United States, and Europe are planning to this bus in mass - produced vehicles, and it is expected to become a standard communication bus for the car audio industry in the near future.

LiDAR stands for abbreviation of "Light Detection and Ranging." It is an optical sensor technology that measures the distance to an object by irradiating it with laser light and observing the reflected light.
This article introduces you to Analog Devices's prototyping platform for LiDAR applications, which reduces the barriers to LiDAR deployment and accelerates development.

The power supply of the operational amplifier must be established at or before the input signal is entered. Otherwise, overvoltage or latch problems may occur.
When an operational amplifier is used as an input circuit for an external sensor (Figure 1).
The power on state of the op amplifier is in the correct order before the sensor signal is fed into the op amplifier. But is it guaranteed that this procedure is always followed correctly?
In this case, the channel protector product makes it easy to protect the op amplifier from accidental input signals.

In recent years, regulations on standby power have become stricter mainly in the EU. Small battery - operated devices such as portable devices and sensor terminals need to be powered on and off in order to use energy efficiently.
This can be easily achieved by using LTC2955.
