Greetings,
I am using UC3906 to charging my SLA battery 6V 4.5Ah, the following are the specification:
Voc=7.45V V12=7.08V Vf=6.9V V31=6.21V Vin=12V Imax=500mA
R2=0.51Ω R7=82KΩ R12=10KΩ R13= 39kΩ R8=220Ω R6=390KΩ
other the resistor value are same as below circuit.
My input is connected with an adapter 12V 1A.
The problem i facing is that when i on the power, my led float(green) and bulk(orange) are on without connect to the battery.May i know it that my resistor calculation are wrong or anyway i can check the problem that i facing.
Thank You .
Hope can get the reply as soon as poosible.
