Load switch with self-resetting circuit breaker
Anthony Smith has designed a simple load switch using two transistors and some resistors. The simple current-limiting load switch shown in Figure 1 will be familiar to most readers.
Anthony Smith has designed a simple load switch using two transistors and some resistors.
The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load. The load current is limited by negative feedback applied via Q1.
