= 2.5 / [ 56 / (131.5 + 56 + 0.68 ) ]
= 8.400V
Vout = 8.400V
Low Battery signal :
If R5 = 0
and R6 = open :
Vout(LoBatt) = Vref / [ R19 / (R17 + R19 ) ]
= 2.5 / [ 10 / (12.4 + 10) ]
= 5.6V
Vout(LoBatt) = 5.6V
End of Charge signal :
Vout(EOC)
= Vref / [ (R2 + R3 ) / (R1 + R2 + R3) ]
= 2.5 / [ (56 + 0.68) / (131.5 + 56 + 0.68) ]
= 8.300V
Vout (EOC)= 8.300V
Notes:
The current control values must be chosen in ac-
cordancewiththeelementsoftheprimaryside.The
performancesof the batterychargerin theirglobal-
ity are highly dependent on the adequation of the
primary and the secondaryelements.
The additionof thediode D9 is necessary to avoid
dramatic discharge of the battery cells in case of
the chargerdisconnectionfrom the mains voltage,
and therefore, the voltage measurement is to be
operated on the cathode side of the diode not to
take its voltage drop into account. The total bridge
value of R1, R2, R3 must ensure low battery dis-
charge if the charger is disconnected from main,
but remains connected to the battery by mistake.
The chosen values impose a 44

Adischarge cur-
rent max.

Ahysteresis resistor can be connectedto the ”End
Of Charge”comparatortoensureproperhysteresis
to this signal, but this resistor must be chosen
carefully not to degrade the output voltage preci-
sion. It might be neededto impose unidirectionnal
hysteresis (by inserting a diode on the positive
feedbackof the comparator).
