CONTROL CIRCUIT FOR STROBO CHARGING AND DIGITAL CAMERA HAVING THE SAME AND CONTROL METHOD FOR STROBO CHARGING

摘要

PURPOSE: flashlight charging control circuit, digital camera include it is identical and it is a kind of for control the gate charge provide prevent the gating of electric power storage battery over charge due to mistake varying circuit device a part, pass through limitation the charging time and voltage gating. ;CONSTITUTION: charging circuit for flashlamp (210) forms gating and battery between charge current path. Charging circuit for flashlamp charging complete rejects signal according to first. The charge limit time is changeably arranged and and cell voltage in a kind of charge limit time setting unit (202). A kind of charge signal generator (201) output first rejects signal according to the time for completing charge limit. Charge signal generator output second rejects signal according to charge completion signal gate pulse charging circuit. ;The 2010 of copyright KIPO submissions
