Hello Every Body,
In the circuit diagram of 12 V battery charger in page 13 of the datasheet of LM338,
I calculated the output voltage of the charger, it will try to reach 16.4 V,
and in this case the LM338 will enter the current limit mode. After the battery current reaches 380 MA the output voltage will switch to 14 V
provided that at the anode of 1N457 is at 1 V with respect ground
(the voltage drop on the diode and the output of the LM301A). The 16.4 V, and the 14 V are not acceptable for the lead acid battery, and they must be (14.6 to 15 V), and (13.6 to 13.8 V) respectively. I need your advice, and It will be highly appreciated. Best Regards, M.Mokhtar
