Question

Problem #2: For the following PNP Bipolar Transistor circuit, please answer the following questions. An PNP transistor is often referred to as "high side drive" because the switch is placed between the power supply known as the high side and the load (e.g., a resistor) near ground. In this configuration, the transistor is said to "source" current to the load. ENGR 415 – Mechatronics HW due in 1 week 2 When asked about a voltage or current that you expect, you should use data from the transistor datasheet. The PNP Transistor is a SS8550. a) When Vin is at 0V, what minimum current do you expect to flow in resistor R4? b) When Vin is at 0V, what minimum voltage do you expect to see at the collector of Q2? c) When Vin is at 0V, what minimum current do you expect to flow in resistor R3? d) What is the current gain (Ic/IB) from parts a) and c)? e) Based on a), what is the expected power dissipation in resistor R4? f) Based on b), what is the expected power dissipation in transistor Q2? g) Based on c), what is the expected power dissipation in resistor R3? h) If Q2 is ideal and Vin was at 5V, what current would you expect to flow in resistor R3?
