Abstract:
The present disclosure is directed to a current limiting circuit. The current limiting circuit may include a load, a first switch that controls current supplied to the load, and a first resistive network. The current limiting circuit may further include a voltage divider connected across the first resistive network and including a thermistor. The current limiting circuit may further include a first bipolar junction transistor that controls switching of the first switch. The output terminal of the voltage divider may be connected to a base junction of the first bipolar junction transistor.
