Hello we have implemented the recommended circuit in the datasheet for instant-on with some minor changes. When a battery is connected and a charge cycle has started the indicator pin goes low as expected, BUT after the charge cycle completes the charge indicator does not release. Regardless of time that has passed. Our pack voltage is 33.6V peak and 28V nominal. I would also like to mention that it has been observed in some cases where the charge indicator pin oscillates from high to low. How can we ensure the signal is asserted and released when it is supposed to be? I have attached the schematic of the implemented design as well as what the STAT1 and STAT2 pins are connected to.
Thank you for your time!
