Abstract

PURPOSE: To prevent overdischarge by exactly interrupting discharge current and by permitting the supply of current to load by operating switching circuit by pulse from a differentiation circuit capable of generating pulse only at the time of power source switch making.
CONSTITUTION: The overdischarge-preventing circuit consists of the differentiation circuit 16, the switching circuit 16, and the voltage detection circuit 17. The differentiation circuit 15 consists of the condenser C11 which is capable of generating pulse only at the time of making of the power source switch 12 and also connected with the other end of the switch 12 between earths and a serial circuit of the resistors R11 and R12. The switching circuit 16, having a holding function to control the operation of the relay 13, is connected its trigger terminal 16a to the output terminal 15a of the differentiation circuit 15. Also, the switching terminal 16b is connected to the other end of the driving coil 13a of the relay 13, and also the switching circuit 16 is provided with the reset terminal 16c. Thus, overdischarge can be exactly prevented.
