Charger For Deep-Cycle 12V Batteries
Deep cycle batteries are expensive and are designed for a long life. If properly charged and looked after, they should last 10 years or more. Their chemistry is quite different from that of car batteries and if you use a charger intended for car batteries, you will definitely not get their maximum capacity.

Main Features :

Suitable for 12V lead acid batteries
LCD shows charging phase and settings
Temperature, voltage and current metering
3-step charging
Optional equalisation phase
Battery temperature compensation
16.6A charge capacity
Initial trickle charge when battery voltage is low
4 preset battery chemistry settings
2 adjustable specific battery settings (can be set for 6V batteries)
Correction for voltage drop across battery leads>
Wide battery capacity range (4-250Ah) in 18 steps

Zanima me če je kdo izdelal zgoraj omenjeni polnilec. Jaz sem se odločil da bi ga izdelal vendar sem pri ogledovanju sheme in slike vezja naletel na razlike.
Pri IC3 je napajanje(5V) vezano na pin 5, 14, 15 in 16 v shemi pa samo na 16.
GND pa na 6, 7, 8, 11 in 12 v shemi pa samo na 6, 7, 8 in 11.
Povezava iz IC4 na IC3(iz pina 2 na pin 3) je na sliki povezana iz pina 2 na pin 4(pin 3 je pa v luftu)

Zanima me če je tako povezano zaradi stanj de/multiplekserja?

Nisem ravno v detajle gledal, ampak po pravilih dobrega dizajna se neuprabljene vhodne pine nekega čipa vedno poveže na potencial (Vdd ali Gnd, odvisno kateri je bližje za povezat). Nikoli se jih ne pusti v zraku. Izhodne pine pa se pusti v zraku.
Preveri z datasheeti, kateri pini ti delajo preglavice.

Ce je se kdo zainteresiran da bi stvar skupaj zmetal vam prilagam PCB-je.PCB-ji so v .LAY obliki, Sprint-Layout 5.

Greetings, Moderator,
How I can download the attachments in this topic?
It looks like it needs moderator's authorization to do so?
Can you guide me how to get the files?
Thank you !
