Charge and discharge control for coin-type lithium batteries and manganese dioxide lithium batteries MM1177
Operation Outline
The constant current, constant voltage charging control charges at a constant current of 4.5mA, until battery
capacity reaches 0%~90%. It then switches to constant voltage control and sets the charge current to "0"
when 100% charged. Output impedance is set at about 50
so charge current gradually drops and eventually
reaches 0mA. The charging current maximum value is set by battery capacitance. Therefore, When the value
falls below 4.5mA, insert a resistor (R) in series in order to lower charging current value.
The discharging control has a built-in switching circuit between the battery and output. After switching off
during excess discharge, all circuit operations are prohibited. Operation reset is achieved by resuming
charging. In the event of an output short, output current is limited (about 5mA~10mA) by the internal switch
function. This reduces the risk of battery heat emission caused by an output short. Also, the switching circuit
and the battery voltage monitoring switch are on different systems. This means that the discharge output
(OUT1) will not prohibit discharge even during a short, and noise from the output load section will not affect
the detection circuit (OUT2).
