Title: Charging circuit
Inventor: YAMAUCHI KAZUMASA
IPC: H02J7/10
Filed: 1990-09-19
Abstract: PURPOSE:To simplify the circuitry pertaining to detection of full-charge by detecting ON time or OFF time without detecting the battery voltage directly. CONSTITUTION:Switching period T and ON time of a FETQ1 are initially set and a PWM circuit 4 is actuated to begin switching operation of the FETQ1. Charging current is then compared with a set value and if the charging current is lower, ON time of the FETQ1 is lengthened otherwise the ON time is shortened. A CPU 3 compares a previously stored ON time with current ON time and when the ON time varies from increase to decrease, the CPU 3 decides whether the decreasing amount is larger than a set value. If the decreasing amount is larger than the set value, the CPU 3 decides that the battery has fully charged and turns the switching operation OFF or makes a switching to trickle(minute) current.
