Circuit Description
■ Power Supply Section
■ Charging Switch Section
1. The power supply generates constant current (1.1A)
from the input voltage (rated 15V DC) from the adapter.
2. IC101 is a DC/DC converter.
3. R117 is a resistor for current detection.
4. R110 and R111 are resistors for no-load voltage detection (non-load voltage : 14V).
5. IC201 is a power supply/reset IC for the microcomputer
(IC202).
· Power output : 5V
· Reset output : “H” (Normal)
· After reset : “L”
1. Q201 is a transistor that turns quick charging on and off.
2. Q202 is a transistor that turns trickle charging on and off.
3. The resistor (R204) determines the leakage current.
■ Charging Control Section
1. The microcomputer (IC202) controls the following;
· Peak detection (Detected when fully charged, pin 27 of
IC202)
· Temperature control (Pin 2)
· Detection of abnormality, such as a short terminal (Pin
27)
· LED control (Red : Pin 21, Green : Pin 22)
· Trickle charging (Pin 18)
· Quick charging (Pin 17)
2. X201 is an oscillator that generates clocks for the microcomputer (4MHz).
■ Display Section
1. LED201 is a two-color LED that indicates the charging
state.
2. Red on ............... Quick charging or warming up
Green on ............ Charging is complete
Red blinking ....... Abnormal (short terminal, short battery, or open terminal)
Charging
The charging time for each pack is shown in the table.
