Prevents high current from damaging the MOSFETs.
and 300K to GND) to limit the maximum duty cycle during the "strike" (lamp ignition) mode.
The pin is pulled high (≈5V) by the internal current source. Fault Condition: The IC turns on the internal open-drain transistor, grounding the PROT pin (≈0V). Latch: Once the PROT pin is pulled low (by internal or external means), the IC latches off all PWM outputs. The only way to restart is to cycle the ( V_CC ) power (power-on reset).
For detailed electrical specifications and pinout diagrams, you can refer to the LX1692 Datasheet at Alldatasheet or Datasheet.HK .
