at Hot/Cold and Automatically ICHARGE/8 at  
Hot/Cold or Warm/Cool  
The bq24630 charges the battery in three phases:  
preconditioning, constant current, and constant  
voltage. Charge is terminated when the current  
reaches  
a
minimum user-selectable level.

charge cycle if the battery voltage falls below an  
internal threshold, and enters a low-quiescent current  
sleep mode when the input voltage falls below the  
battery voltage.
