Title: Switching circuit
Inventor: TAKADA SHIGEO
IPC: H03K17/66
Filed: 1978-03-08
Abstract: PURPOSE: To obtain a switching circuit which can ensure the deflection of the amplitude for the output signal in the full range between the power source level and the earth level with a small amount of the power consumption.  
     CONSTITUTION: When transistor Q11 is off, Q18 is turned on via resistance R13 and diode D17 but Q16 is kept off via D12. When Q11 is on, Q16 is turned on via R14. In this case, the potential of the connection between R13 and D12 becomes equivalent to the sum of VCE of Q11 and VF (forward voltage) of D12, which is lower than the sum of VBE of Q18 and VFof D17. Thus, Q18 is kept off, and the output of circuit 15 is deflected to the full up to VCC and the earth level. When Q11 is on, IC 11  features the sum of IB 16  and IFD passed through D12. While R13 suffices with the level according to the base current of Q18, and thus nearly the same high resistance value is secured between R13 and R14 to be reduced down to the level low enorgh. As a result, a miniature switching circuit is obtained with a small amount of power consumption.

Title: Overcurrent protection device for power transistor
Inventor: ICHIKAWA HIROAKI
IPC: H03K17/14
Filed: 1995-02-15
Abstract: PURPOSE: To accurately protect a power transistor from overcurrent without being affected by the variance of temperature. CONSTITUTION: Some of many unit structures constructing a part of a power transistor TR 10 are allocated at a current detection part 10a and a detection terminal Td is led out. The currents are supplied through the terminal Td to a detection resistor 20 and a temperature compensation means 40 such as a thermistor resistor, etc., that has the negative temperature dependency. Thus the positive temperature dependency of the current is compensated. In such a constitution, the potential of the terminal Td is never affected by the variance of temperature and an overcurrent detection means 50 generates an overcurrent signal So when the potential of the terminal Td exceeds the prescribed reference value Vr. Then the signal So is given to a protection TR 30, and the TR 30 is turned on. As a result, the current of the TR 10 is cut off or limited by the control of a control terminal Tc.  Thus the TR 10 can be protected from the overcurrent.
