((top)): Lx1692 Protection Pin
A logic low (< 0.8V) disconnects internal power, disabling all functions immediately. Fault Stop Threshold
| State | PROT Pin Voltage | IC Outputs (PWM) | |---|---|---| | Normal | ~5V | Switching | | Fault detected (first few cycles) | ~5V (no change) | Switching | | Fault confirmed | 0V | Hi-Z (off) | | After ( V_CC ) reset | ~5V (rising edge) | Switching resumes | lx1692 protection pin
Do not pull PROT high externally (e.g., connect to 5V directly). This can conflict with the internal pull-down and damage the pin or prevent proper fault detection. A logic low ( | State | PROT
