Design Notes
The LTC4096EDD#PBF is a linear charger, so power dissipation is proportional to the voltage drop across the internal MOSFET. At 5V input and 4.2V battery voltage, the drop is 0.8V, and at 1.2A charge current, dissipation is approximately 0.96W. The 10-DFN package has an exposed pad that must be soldered to a copper area on the PCB to dissipate heat. Ensure adequate copper pour and thermal vias to keep the junction temperature within limits.
Place the input and output capacitors close to the VCC, USB, and BAT pins to minimize parasitic inductance. Use a 1uF ceramic capacitor on each input and a 10uF capacitor on the battery output. The PROG pin resistor should be placed near the IC to reduce noise. The exposed pad should be connected to ground with multiple vias for thermal and electrical performance.
Do not exceed the maximum input voltage of 5.5V on either input. Ensure the PROG resistor is correctly sized for the desired charge current; an incorrect value can lead to overcharging or slow charging. The NTC pin, if used, requires a 10k NTC thermistor to monitor battery temperature; if not used, connect it to ground. Also, verify the charge status outputs (CHRG, FAULT) are properly pulled up if used.
