SMD Marking: FZUH (ALL capital)

Package: SOT-23

Pin-1 connected to Ground
Pin-3 Connected to VCC
Pin-2 connected to uC (don't know pin because connected to ASIC chip)
 

Obviously a supply supervisor/reset controller, similar to MAX809 or 810.
 

Possibly a Richtek RT9819 which is as FvM suggests a reset generator. They come in SOT23 packages marked FZ followed by numbers or letters to indicate their switching threshold.

Brian.
