Note 1:
The input voltage range is specified with the external PMOS FET off. When charging, the PMOS FET turns on, and the input
voltage (the output voltage of the current-limited source) drops to very near the battery voltage. When the PFET is on, V
IN
may be as low as 2.5V.
Note 2:
Restart Threshold tracks battery regulation voltage adjustment.
Note 3:
Glitches less than 1ms do not cause a restart.
Note 4:
This current is less than 1.5μA, even if an external R
ADJ
resistor is connected from ADJ to GND.
Note 5:
Specifications to -40

C are guaranteed by design and not production tested.
