STripFET F7 Negative Vgs Voltages

Hi Everyone, I am using the STL120N4LF6AG device in a product and I was wondering if there is any have to turning it off with a negative Vgs voltage? The data sheet only lists a positive Vgs limit (40V) so it is unclear what it's tolerance to a negat...

How to wake up Li-ion battery that has entered over-discharge protection?

I am using a STBC08 to charge the battery in my application. It works fine, but if the battery isn't charged for a long time the battery goes into over-discharge protection. In this state the battery terminals are at 0 V and trying to charge the batt...

Driving Multiple Sensored BLDCs

I have a project where I would like to drive two separate sensored BLDC motors with a single microcontroler. The only options I have seen involve the control of a single motor with no options of stacking shields (in the Nucleo's case) or using mu...
