The two resistors in Figure 1 are external from the NSM4002MR6 to allow for customization. Rset controls the current through the load, and R1 controls the bias current. based on the biasing current. To determine the Rset value simply divide the VBE voltage by the desired driving current. ## **Selecting R1** The R1 resistor is used to set the biasing current. The biasing current is split between the base of Q2 and the collector of Q1. When desiring the lowest overhead voltage R1 should be set as high as possible. It is important to ensure it is not set too high so that Q2 falls out of saturation. However, a lower R1 value will drive more current through Q1. This will reduce the change in the driving current as temperature is increased. It will also allow a higher driving current to be achieved while maintaining good current regulation. The side affect of a lower R1 value is that it reduces the overall efficiency because more power is being used in the driving circuit. ## **Input Votlage, Vs** The maximum input voltage, Vs, is determined by the load. No more than 45 V can be applied across Q2. This leads to: **==> picture [162 x 12] intentionally omitted <==** **Figure 1. Typical Application Schematic** ## **Selecting Rset** The Rset resistor is used to set the driving current of the load. It is connected across the Base−Emitter junction of Q1. This VBE voltage is what sets up the constant voltage across the Rset resistor. Figure 5 gives the typical values of VBE ## **Overhead Voltage** The overhead voltage of this device to reach full current regulation is the combination of the VBE voltages of the two transistors. Under typical conditions this overhead voltage will typically be 1.4 V. **www.onsemi.com** **3** **NSM4002MR6** ## **TYPICAL CHARACTERISTICS − Q1** **==> picture [487 x 375] intentionally omitted <==** **----- Start of picture text -----**
