rusherI made a simplified, interactive demo version of the my single op-amp battery charge control circuit on Falstad:
The outputs can be used to control a charging circuit, looking at it like a truth table:
| A | B | System Status | Example Input Voltage Range |
|---|---|---|---|
| T | T | Charging | 2.7V to 3.6V |
| T | F | Under Voltage | 0 to 2.7V |
| F | T | Overvoltage | Triggers when Input > 3.6V, resets when Input drops below 3.4V |
| F | F | N/A | N/A |
