DESCRIPTION  
The bq29312 is a 2-, 3-, or 4-cell lithium-ion battery  
pack protection analog front end (AFE) IC that  
incorporates a 3.3-V, 25-mA low-dropout regulator  
(LDO). The bq29312 also integrates an I2C compat-  
ible interface to extract battery parameters such as  
cell voltages and control output status. Other par-  
ameters such as current protection thresholds and  
delays can be programmed into the bq29312 to  
increase the flexibility of the battery management  
system.

Host Control Can Initiate Sleep Power Mode  
and Ship Mode  
The bq29312 provides safety protection for over-  
charge, overload, short-circuit, overvoltage, and  
undervoltage conditions in conjunction with the bat-  
tery management host. In overload and short-circuit  
conditions, the bq29312 turns the FET drive off  
autonomously dependant on the internal configuration  
setting.
