Hello,
I wanted to first outline what the objective of my design/project is:
I'm designing the load-switching/power-switching PCB's that will essentially power-cycle sensitive loads like an MSP430 micro-controller, an IMU, and other sensitive electronic instruments.
These loads are to be power-cycled (switched on and off) to ensure that they can escape a latch-up condition caused by space radiation (these PCB's are to be installed into a lunar rover).
Although radiation-hardened components were considered, COT's components like this will be verified through extensive testing.
I'm hoping I can get some insight into how long devices like an MSP430, or other microcontrollers and sensors in general, can succumb to a latch-up condition. I'm assuming that this time is essential to the auto-reset behavior the smart switch implements because too short of a time being switched off can induce some weird oscillatory state in the load. Referencing the datasheet, I'm referring to the minimum time for t_hlc in Figure 18.
To drive a load like a micro-controller, are there any suggested best practices/most important things to consider? I went through the presentation on driving different types of load but would still appreciate any advice since I'm not sure how it would behave as a load.
I was also wondering if there's an IC similar to this one that can support a supply voltage as low as 3.3V, for use with a load like the MSP430 specifically. Appreciate any and all help, thank you.
