The circuit shown in Figure P10.27 is a variation of the motor driver circuit of Example 10.5. The external voltage vin represents the analog output of a microcontroller and alternates between 0 and 5 V. Complete the design of the circuit by selecting the value of the base resistor Rb such that the motor will see the maximum design current when vin = 5 V. Use the design specifications given in the example.
Assumptions:
Assume that the transistors are in the active region. Use the large-signal model with ? = 40 for each transistor.
