COBOTs - Safety Rated Monitored Stop

Tom-M

This blog continues my series of robot safety posts. In my last blog, I jumped ahead to the more exciting SSM (speed and separation monitoring) safety function. This month I need to get back to basics and discuss stopping functions. Stopping is something…

ADuM4223 for safety class II

GenevaCooper

Q

For a synchronous rectifier I am looking for a gate driver. The equipment shall
have safety class II.
Has the ADuM4223 a sufficient isolation?

A

The ADuM4223 will meet safety class II. To do this you need to meet 6000V
impulse voltage (surge…

AD5421: Intrinsic safety - voltage / capacitance minimizing

GenevaCooper

Q

A customer request design support for intrinsic safety.

He needs to minimize the capacitance inside the system. As a basis he uses the
Evalboard and an own PCB based on the datasheet:

Question: Which capacitors can be shrinked without loss off function…

An Introduction to Machine Safety Standard ISO 13849

Tom-M

In the next couple of months, I will introduce the concept of functional safety and robots, including cobots (collaborative robots) and mobots (mobile robots). However, I haven’t covered ISO 13849 in previous safety matters blogs, and most robot safety…

RE: LTC1760 without safety signals

MCox1

Just to clarify, does one of the two 300 ohm "thermistors" connect between the "BAT1" node and the node between the TH1A & TH1B resistors, and the other 300 ohm "thermistor" between the "BAT2" node and the node…

If You Could Only Keep One Thing From Functional Safety?

Tom-M

If functional safety was declared illegal tomorrow and I could only keep one thing from the functional safety standards, it would be requirements management. Of course, requirements management predates functional safety but to put it another way, in my…

AD9136 Minimum Safety pullups/pulldowns

rdb9879

We are designing a PCB that will include an FPGA interfacing with the AD9136. It's critical for us that the DAC outputs cannot become "accidently" enabled before the FPGA has finished its powerup configuration (the FPGA pins driving reset, txen, jesd204b…

I am not designing a system for functional safety. Are the diagnostics still useful?

GenevaCooper

Q

I am not designing a system for functional safety. Are the diagnostics still
useful?

A

The on-chip diagnostics are useful in any system, even an application where
functional safety is not important. The on-chip diagnostics allow the user to
