Description

This circuit will detect a current flowing through a current mirror and outputting a low-level signal once it reaces a certain threshold. This is intended to work as a controller detection circuit for various consoles in combination with DarthClouds BlueRetro adapters for internal installation.

Idle Currents per Console

ControllerIdle Current
N64 (OEM)6 mA
DS2 (OEM)8 mA
GC (OEM)7.5 mA
MegaDrive (OEM)<1 µA
NES (OEM)<1 µA

The circuit is designed to reliably output a low-level at a threshold of 300µA! Any controller consuming less in idle state is not detectable.
