LT3652 6V SLA Battery Voltage Feedback

00:51:45

Feedback Input needs 250k Ohm equivalant to correctly bias diff pair of LT3652 feedback (Vfb) amplifier. 

One of the 100k is a thermister (B=4250, i.e. 6.71V:50.7k@40C, 6.8365V:100k@25C, and 7.048V:357k@0C) placed on SLA type battery to match charge voltage  with temperature.

When the current in both legs of diff pair are matching then the network is at threshold voltage.
