Hello,
I'm looking for a load switch to provide soft-start and reverse-polarity protection, the output from the isolated DC-DC is +5V and the current is ~2A. Ideally I'd like to use a commercial-grade device for an initial prototype and then swap to a space-grade version.
Which part numbers can you recommend?
thank you
Hi,
We currently offer 2 space-grade load switches that fit your description:
Each of these devices comes with options for full space-grade parts and unqualified evaluation units (part orderable number ending with "/EM") that are intended for prototyping use. There are no commercial equivalents as these devices are designed specifically for the space environment.
Thanks,
Sarah
In that case, I would recommend utilizing the product selection tool to help you narrow down your choices since the part numbering system is not as structured as it tends to be for simpler components like capacitors or resistors.
You can filter devices based on many characteristics like voltage/current, features (such as soft start), rating (automotive, space, etc.). You can also select which properties are displayed as columns for easier comparison.
Reverse current protection is intended to protect against cases where the output voltage is higher than the input voltage while the device is switched on. This is different from reverse input polarity protection. The devices I listed earlier are capable of the former - apologies on the mix up.
