い工うに対策tしなければならない。As a conventional power supply device, do you have sufficient power supply to use a large capacity capacitor instead of using AL as a slave clock or a constant voltage device? By making them wait, they were preventing fluctuations in d power. -For example 1.
When the voltage of 5V is changed by about t1vruk and the voltage is constantly operated at 1.1V, and the lamp for the liquid crystal display which consumes a large amount of power is turned on, the HIIT source voltage fluctuates and affects the clock movement. Lamp power source is battery 1.5
It was supplied directly from v. *In order to prevent short-term power fluctuations, a capacitor was connected in parallel with the battery to prevent ripples in the power supply. On the other hand, recently reliable 6v
Linium batteries, which are similar to linium batteries, have been put into practical use, but there are small lamps for lighting and buzzers for alarms! kf'll: When the battery is moved, the internal resistance of the battery is relatively soft, so the voltage drops to nearly 2V. Therefore, measures must be taken to ensure that the circuits for driving the clock movement, such as the display drive circuit, are not affected by this.

V is output. Also, T when lighting the lamp and driving the buzzer.
, 1.55 V is output. It also controls the timing of TsH constant voltage supply, and after receiving a heavy load signal from a lamp or buzzer, clock pulse 1024H is applied.
The supply from the constant voltage cell line is delayed by one clock of 2. Furthermore, when the voltage is restored to 1.5V for the step-down circuit operation, the supply from the constant voltage circuit is cut off 1.5 seconds after the a large load signal is released.

Vastの端子に1.557を出力する。The D block is a circuit that detects the presence or absence of an input clock signal of 1024 Hz. When a 1024 Hz signal is input, a pulse sound is generated at the output of EX/OR due to the delay caused by the capacitor Ot and the resistor, and the signal is photoelectronized to a low level to the capacitor CI. Therefore, 1 (1241 (When the z signal is input, the output of the μD block becomes high level.1024
When the H2 signal stops, the output of Ex・OR is fixed at low level, and the capacitor C! α is discharged by the resistor connected in parallel and becomes a high level, and the output of the D boom becomes a low level. Therefore, flip-flop FF1~

Since the signals that control Il'8 to FIP12 are taken out, the setter ^ and the constant voltage circuit B block operate when all input signals are at high level, and the transistor TI turns on L/%.
Output 1.557 to the Vast terminal.

磯批について利用価値が鳥いものである。In the present invention, when a large current load is applied between power supply voltage +vDD+ and 5112, the power supply voltage fluctuates rapidly and cannot reach a predetermined low level, for example, when the power supply voltage drops to 2V, When the output reaches 1■, oscillation stops and has a negative effect on the function of the clock.
It outputs an output of 5v to 1.5v, and is designed to prevent oscillation from completely stopping and preventing the entire clock from going off. The present invention uses a power source with a high voltage battery and a relatively high internal resistance.
The utility value of Isochuri is amazing.
