MITSUMI
Note 1: Current limits 1 and 2 and full charge detection are specified at current detection resistor voltage
Note 2: If the IC is damaged and control is no longer possible, its safety can not be guaranteed. Please
Note 3: Temperature detection is the setting value at B constant 3435 (10KC15-1608 made by Ishizuka
Note 4: Use a capacitor with good temperature characteristics in the oscillator. Capacitor deviation will
Note 5: If the battery overdischarges, charge 1mA for 14 seconds, and if it does not switch to pre-charging
