This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION (CONTINUED)
The bq24630 controls external switches to prevent battery discharge back to the input, connect the adapter to
the system, and to connect the battery to the system using 6-V gate drives for better system efficiency. The
bq24630 features Dynamic Power Management (DPM). These features reduce battery charge current when the
input power limit is reached to avoid overloading the AC adapter when supplying the load and the battery charger
simultaneously. A highly-accurate current-sense amplifier enables precise measurement of input current from the
AC adapter to monitor the overall system power.
NOTE: VIN=19V, BAT=3-cell LiFePO4, Iadapter_limit=4A, Icharge=3A, Ipre-charge=0.125A, Iterm=0.3A, 2.5hr safety timer
