The H-bridge is a classic circuitused for driving DC motors in auser-defined manner, such as in forward/reverse direction or PWM-assisted controlledRPM with the help of four discrete/integrated ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

The circuit is designed for power supply protection by limiting the amount of maximum output current to prevent any further damage to take place inside the power supply as well as the external circuit ...

Current-limiting regulators protect the circuits they feed but don't necessarily protect themselves against excessive dissipation. Here is an Idea For Design with a regulator that does both. A current ...

MJE1123, once from Motorola and now from New Jersey Semi-conductor Products, is a rather specialised transistor. It is a 40V 4A power pnp with high gain and good saturation (200mV max at 1A). The ...
