Hi,
I'm using LTC4015 circuit for battery charging. I'm facing 2 issues with that.
Schematic :
1. When connecting battery, sometimes LTC4015 getting damaged.
I understood that they are capacitor connected across battery, so due to transient behaviour it may happen. (Inrush current flow when capacitor acts like short circuit at the time of connecting battery).
Please check schematic, if you got any idea/observation, kindly share me.
2. Using 33mohm current sensing resistor, to restrict battery charge current to 1A(32mV/33mohm). but i observed more than 1A(2.4A). Even am changing resistor value, not observed any changes in current.
