We are using this for our wireless charging receiver. We are able to charge but unable to get the fully charged info on the transmitter. For a brief moment it shows that it is fully charged but immediately goes into charging mode. this happens continuously. We have connected TS/CTRL pin to GND with 10K res making the function unusable. We are charging a 3.7V li-ion single cell battery. Can you have a look and let us know if this is the issue and can be resolved by pulling high the TS/CTRL pin to Vbat with 10K res? if so, how can we stop it at 4.2V
