PURPOSE:To integrate a detecting resistance by using a shunt transistor formed with characteristics matched on the same substrate through having a base and an emitter connected in common in a current limiting circuit using base-emitter voltage of the transistor as a reference voltage. CONSTITUTION:A...
A current-limiting diode circuit includes a diode in series with the load. Instead of a fixed resistance, the diode conducts when the current exceeds a threshold. This increases the voltage drop across the diode, thereby limiting the current flowing through the load. A transistor in these circu...
CURRENT/VOLTAGE CONVERTER WITH CURRENT LIMITING CIRCUIT PURPOSE:To attain stable IV conversion without losing a circuit function by using a voltage detection means and a current bypassing transistor(TR) to bypass a current signal exceeding an upper limit when the current signal of the upper l... ...
The ignition circuit has a drive transistor (14) controlling a Darlington pair (17,19) which switch the primary current of the ignition coil (20). A Zener diode (31) linked to a resistor chain (13,30) holds the base of the drive transistor at the optimum setting irrespective of changes...
PURPOSE:To prevent destruction of a transistor(TR) or a load at switching of a constant current circuit by connecting a capacitive element between a collector and a base of the TR suppressing a current. CONSTITUTION:An anode of a diode 2 and one terminal of a resistor 3 are connected to ...
I am using a diode to bias a BJT in order to regulate voltage to a load. See attached image (top) This top circuit in the attached figure works well and this c
A power transistor switched power supply connecting a power source to a capacitive load, including a circuit and method for limiting the inrush surge current through the power transistor. The control gate of a junction field effect transistor (JFET) is coupled between the conductive path of the ...
any section of a circuit. When it comes to putting a prototype these days you can pretty much just buy each block of your system’s overview flowchart and string them together. [GreattScott!] combines a few of these into a relativelyuseful variable power supply with current limiting. ...
SOLUTION: A current deciding means which consists of a serial circuit of at least two diodes D1 and D2, resistor R1 and an emitter-base section of a 2nd transistor T1 is connected between the collector C1 and the base B1 of a 1st transistor T1 to be controlled so that an operating ...
