Limiting battery input current to avoid voltage drop when activating
It takes in the battery''s voltage range (2.0V to 3.6V) to an operating voltage of 3.0V. However, the IC doesn''t have an input current limiter that can limit the current so that it doesn''t take too much peak current from the battery. At low temperatures, we can''t take in too much current from the battery or else the voltage drops substantially.
