发明名称 Watch fitted with an electric motor control case
摘要 The invention concerns an electronic watch (8) including: a motor (5), a power circuit (7) supplying first and second voltage levels; a case (11), in which there are mounted: first and second (A, D) output connections; a switch (9) actuated by an external actuator to connect the first connection to the second level (Vdd); a control circuit (4) for the motor including first and second three-state gates (12, 14) respectively connected to the first and second connections (A, D), a member (13) selectively connecting the first connection to the first level, the circuit including a test mode wherein the gates are brought to high impedance, the first connection (D) is connected to the first level (Vss), actuation of the actuator is determined as a function of the voltage measured at the output of the first gate.
