EagleTree Brushless sensor
 
1 Attachment(s)
Hi
After 4 flights my EagleTree Brushless sensor don't work anymore.
I have checked all components, except for U1, it's a 5 pin IC with marking code AAEH. Can anyone help with some data for this IC ??
Thanks in advance

The SOT23-5 package is too small for a part number so the MFGs use codes. I may not be possible to fine the part number without knowing who made the part.

No sign of who made the part. I think it is some kind of a 2 input thing, because the upper 2 pins has identical circuit and goes to each input channel (one pin to motor 1 and the other to motor 2)

It could be an AND or OR gate with inputs on pins 1 and 2, GND on pin 3, output on 4 and Vcc on 5. It can also be an op-amp or ???
