M62255FP

GENERAL PURPOSE BATTERY CHARGER CONTROL IC

Charge Current of Current Detect R is multiplied by 10 and outputted from DOUT.

M62255 is for the floating detection type. Current Detect R is connected to + terminal

of battery.So M62255 is best fit for SMBus system ,because the common GND can

be given between PC system and the charger circuit.

Discharge current is detected by the same method as charge current.Detecting

discharge current can be used for monitoring the current consumption and the

remnant of the battery.
