Hello, I am having a big headache with a charger circuit that I have design for my application. The circuit is presented by the circuit below.
The battery is reaching 4.4V and the charging current goes as low as 30mA (or even less) without stopping the charge.
I tried to:
- Change Rterm to 10k;
- Remove Rterm.
- Connect TMR to GND
- Short the current sensor and the choke to reduce the impedance.
Any advice is much appreciated.
