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.
| Controller | Idle 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.
