Question:
For MAX77818, the input current can be as low as ICHGIN_REG_OFF (50mA typ), but according to CHGIN_ILIM setting, the minimum current is 100mA, what is the difference between the two current values?
Answer:
ICHGIN_REG_OFF sets the minimum shutdown current for charging. When the input current is lower than this set value, the chip is turned off.
CHGIN_ILIM sets the maximum current limit for charging.
