Hi all
I paste the description of this IC:
The MCP111/112 Series are CMOS voltage detectors are well suited for portable, consumer electrics applications due to the extremely low 1uA operating current and small surface-mount packaging. These devices are designed to hold the microcontroller in reset until the supply voltage reaches a predetermined operating level. These devices also protect against brownout conditions that occur as a result of the supply voltage dropping below a tolerable level.
I thought this function is integrated into microcontrollers. Am I wrong?
What does it mean holding the uC in reset?

Yes, some uC will have it but some will not. Also, you have to remember to enable it.
Or the build-in inside the uC threshold voltage level will not suit your application needs

What does it mean holding the uC in reset?
Pulls the reset pin to GND (LOW state).
