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.
