the battery and the battery pack ground contact. By  
using the accumulated counts in the charge, discharge,  
and self-discharge registers, an intelligent host  
controller can determine battery state-of-charge  
information. To improve accuracy, an offset count  
register is available. The system host controller is  
responsible for the register maintenance by resetting  
the charge in/out and self-discharge registers as  
needed.

128 Bytes of General-Purpose RAM  
The bq26231 features 13 bytes of registers, which  
contain the capacity monitoring and status information.  
The RBI input operates from an external power storage  
source such as a capacitor or a series cell in the battery  
pack, providing register nonvolatility for periods when  
the battery is shorted to ground or when the battery  
charge state is not sufficient to operate the bq26231.  
During this mode, the register backup current is less  
than 100 nA. Packaged in an 8-pin TSSOP, the  
bq26231 is small enough to fit in the crevice between  
two A-size cells or within the width of a prismatic cell.

DESCRIPTION  
PW PACKAGE  
(TOP VIEW)  
The bq26231 is a low-cost charge/discharge counter  
peripheral in an 8-pin TSSOP. It works with an intelligent  
host controller, providing state-of-charge information  
for rechargeable Li-Ion, Li-Pol, or NiMH batteries. The  
bq26231 measures the voltage drop across a low-value  
series sense resistor between the negative terminal of
