15 – testing smart high side switch

Feature-packed over-discharge protection. Set the cell-count, minimum cell voltage and dip-time below threshold. Fully hackable!

Just a quickie:

I expect the test-boards for the BTS441RG smart high-side power switch to arrive end of this week.

This thing has some awesome protection features:

The only "downside" is the relatively high Rdson of 20mΩ. But I'll do some thorough tests with this puppy. Stay tuned!

Really looking forward to hearing how these devices perform!

Are you sure? yes | no

Yeah, me too! They have several interesting devices, but they're not exactly cheap...

On the other hand a good MOSFET with a current shunt and good ADC or current amplifier comes into that range too...
