Most watchdog-timer ICs produce a single limited-duration output pulse when the watchdog timeout expires. Some applications, however, require the output to latch. This simple circuit provides a ...

The RJF0605DPD is silicon N-channel MOSFET power switching featuring a built-in over temperature shutdown circuit. It has latch type shut down operation and a built-in current limitation circuit.The ...

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.
