Manual shutdown

At any point in the charge cycle, the FP8202 can be put into shutdown mode when put the EN pin

to the low-level voltage. This reduces the battery drain current to about to 2uA and the supply current to

less than 55uA.

Automatic Recharge

Once the charge cycle is terminated, the FP8202 continuously monitors the voltage on the BAT

voltage falls below 4.05V (which corresponds to approximately 80% to 90% battery capacity).This

ensures that the battery is kept at or near a fully charged condition and eliminated the need for periodic

Programming Trickle Charge Current

If the battery voltage is below the trickle charge threshold, the FP8202 delivers a small current

to charge the battery until the battery voltage reaches the fast charge threshold value. the trickle

programmed charging current to bring the battery voltage up to a safe level. The trickle charge current

value can be calculated with following equation:
