Title: Protection from overcurrent state, and electrically- unloaded-state sensing circuit and method thereof
Inventor: SULLIVAN RICHARD
IPC: H02H3/087
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To protect a first transistor from its overcurrent state and sense its electrically unloaded state, by providing a second transistor for so operating as to notify a microprocessor of a logical signal indicating the unloaded state of the first transistor after the attempt of switching the first transistor into OFF-state is repeated. SOLUTION: A second operational state corresponding to an abnormal operation is the case wherein a load 26 of a first transistor 50 is absent for some reason. In this case, the voltage source of the first transistor 50 which is zero volt because of its no load does not turn-on a second transistor 60. An input pin 18 of an overcurrent field effect transistor circuit 20 (broken-line portion) which is also an input/output pin 12 of a microprocessor 10 notifies always the microprocessor 10 of a logic 1, responding to its request, even after the inputting of a negative pulse to the circuit 20 is repeated in order to turning-off the first transistor 50. This notifies the microprocessor 10 that the circuit 20 is unloaded. In this case, the first transistor 50 is biased to ON-state.  But since its load is absent, no wrong influence is generated in the overcurrent field effect transistor circuit 20 (broken-line portion).
