Note:
The thermal regulation action range is characterized at small current situation, is guaranteed by design verification, char-
acterization and production process control.
See the TYPICAL PERFORMANCE CHARACTERISTICS for:
The Charge Current to Battery Voltage, at 5V Input.
The Charge Current to Battery Voltage, at 6V Input.
The Charge Current to Ambient Temperature, 6V Input.
The Charger Load Transition Response, LDO Mode.
