Note:
VIN ≥ 2.2V
Charging current =0.8A, Auto-Cut-Off at 0.75/0.25% -∆V point and Fault Conditions.
(RIF sets the Charging Current)
VIN must be lower than VBAT.
Short Circuit Condition is protected with a 2A Fuse.

Note:
Fast Charge Current
= 0.8A @VIN<VBAT
=(VIN - VBAT - 0.5)/0.82 @VIN>VBAT
Trickle charge Current = 30mA.
(RIF sets Fast Charge Current, RIT sets Trickle Charge Current)
Typical Efficiency = 75%.
With Short Circuit Protection.
