Hi there,
I have a question regarding the UC2906 chip. right now, I have the circuit laid out in a way that as soon as the state level output of the chip goes high, the device would enter the discharge mode and discharge it (controlled via software - Labview).
this is the problem that Im having. As soon as I turn the power ON with the Battery connected to the charger, the chip's state level output will be HIGH suggesting that it has entered the float stage and the voltage is not climbing and seems to be stuck at that startup voltage.
Clearly the chip should be in the bulk charging mode until the battery voltage reaches the overcharge voltage (14.4 - 14.8 v).
this is definitely causing discrepancies in my project as Im having to rely on other techniques to sense if the voltage has reached the overcharge level.
Has anyone come across this problem??
thanks,
Mat
