Abstract: PURPOSE: A circuit and method for automatically detecting a valid key push operation in a mobile terminal is provided to minimize a meaningless loss of battery capacity by making a mobile terminal not operated for a user's unintended, instantaneous key push operation. CONSTITUTION: A control part judges whether the flip of the mobile terminal is closed(100). If the flip is closed, the control part enables an INT_PU port for a mode control interrupt signal(INT_PU)(102). Then the control part disables an internal interrupt signal(KEYSENSE_INT)(104). The control parts enters a sleep mode(106). If a key is inputted(108), the control part compares the key pushed time with an RC delay time by an RC delay circuit(110). In case that the key pushed time is longer than the RC delay time, the control part generates the mode control interrupt signal(INT_PU) so that the sleep mode of the mobile terminal can be transferred to an idle mode(112,114). Then the control part enables the internal interrupt signal(KEYSENSE_INT) so that all the key buttons can be normally inputted(116). The control part disables the INT_PU signal(118) and executes a function corresponding to the inputted key(120).
