Title: Circuit for detecting main power interruption duration
Inventor: ISHII TATSUO
IPC: H04B1/16
Filed: 1990-04-16
Abstract: PURPOSE:To realize this detection circuit for a time detecting main power supply interruption with simple circuit constitution by using a NAND signal so as to decide whether the interruption time of the main power supply is shorter or longer than a prescribed time when the main power supply is applied. CONSTITUTION:When a main power supply +B is applied till a signal at an input port I1 reaches a high level after the main power supply +B is interrupted, a microprocessor 6a discriminates that 'main power supply +B is fluctuated but not interrupted by intention' and executes normal operation based on a storage state (last-one memory) just before the main power supply +B is interrupted. On the other hand, when the main power supply +B is applied after the signal at the input port I1 reaches a high level after the main power supply +B is interrupted, the microprocessor 6a discriminates that 'main power supply +B is interrupted by intention' and does not execute the normal operation so long as a specific key is not entered. Since the circuit is in operation by a circuit power supply within a time when a timer IC1 is in operation, neither a battery nor a large capacitance of an electrolytic capacitor is required and a small capacitance of the capacitor C is enough for the power supply circuit 1.
