After a charge (and powering it on to see the battery level) I found out that my board didn’t turn on when I wanted to ride it. Opening it up I saw that a component on the Unity’s PCB was toast and was wondering what it was so I can try to mitigate it happening in the future. I have the platinum warranty and currently have a ticket out so I’m not worried about replacement but I’d just like to know.
Thanks in advance!
That’s Jason’s pride burning
According to the chip code it’s a lm5060 from ti, high side driver.
oh shit you blew the master steeze controller. No more steeze now. Damn.
Hey Wannagofast,
I have 2 Focbox Unities with the same burnt Component on the PCB. It has the marking SZAB, and appears to be a generic Component for a LM5060 from Texas Instruments.
DID YOU FIGURE OUT A WAY TO KEEP THIS COMPONENT FROM BURNING OUT???
Also, Did You try replacing it with a TI LM5060 or another SZAB Component, and if so, did the Focbox Unity Controller start working again after replacing it???
Would really appreciate any insight You might have on this…
any of those will work. well except the dev board 
Thanks Jeff, going to see if I can resuscitate this one, do you think this component needs replacing as well?
I’m bench testing a Unity atm with a Photon remote, so far so good, impressive kit 
That’s the 3v3 linear regulator, it looks ok to me but if you aren’t getting 3.3v then maybe?
You should also check if any of the fets across the switch are shorted out, should measure open circuit across the front and back of switch fets.
