1 / 20 page  1 Features ➤ Conservative and repeatable measurement of available charge in rechargeable batteries ➤ Charge control output ➤ Designed for battery pack inte- gration - 120µA typical standby current (self-discharge estimation mode) - Small size enables imple- mentations in as little as 1 2 square inch of PCB ➤ Integrate within a system or as a stand-alone device - Display capacity via single- wire serial communication port or direct drive of LEDs ➤ Measurements compensated for current and temperature ➤ Self-discharge compensation us- ing internal temperature sensor ➤ 16-pin narrow SOIC General Description The bq2012 Gas Gauge IC is in- tended for battery-pack or in-system installation to maintain an accurate record of available battery charge. The IC monitors a voltage drop across a sense resistor connected in series between the negative battery terminal and ground to determine charge and discharge activity of the battery. Self-discharge of NiMH and NiCd batteries is estimated based on an internal timer and temperature sen- sor. Compensations for battery tem- perature and rate of charge or dis- charge are applied to the charge, discharge, and self-discharge calcu- lations to provide available charge information across a wide range of operating conditions. Battery capac- ity is automatically recalibrated, or “learned,” in the course of a dis- charge cycle from full to empty. The bq2012 includes a charge con- trol output that, when used with other full-charge safety termination methods, can provide a cost-effective means of controlling charge based on the battery's charge state. Nominal available charge may be di- rectly indicated using a five- or six- segment LED display. These seg- ments are used to graphically indi- cate nominal available charge. The bq2012 supports a simple single-line bidirectional serial link to an external processor (common ground). The bq2012 outputs battery information in response to external commands over the serial link. Internal registers include available charge, temperature, capacity, battery ID, battery status, and programming pin settings. To support subassembly testing, the outputs may also be con- trolled. The external processor may also overwrite some of the bq2012 gas gauge data registers. The bq2012 may operate directly from three or four cells. With the REF output and an external transis- tor, a simple, inexpensive regulator can be built to provide VCC across a greater number of cells.
