1 / 29 page  1 Features ➤ Accurate measurement of available charge in rechargeable batteries ➤ Designed for electric assist bicycles and other applications ➤ Measures a wide dynamic current range ➤ Supports NiCd, NiMH or lead acid ➤ 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 ➤ Direct drive of LEDs for capacity display ➤ Automatic charge and self- discharge compensation using in- ternal temperature sensor ➤ Simple single-wire serial commu- nications port for subassembly testing ➤ 16-pin narrow SOIC General Description The bq2013H Gas Gauge IC is in- tended for battery-pack installation to maintain an accurate record of a bat- tery’s available charge. The IC moni- tors a voltage drop across a sense resis- tor connected in series between the negative battery terminal and ground to determine charge and discharge ac- tivity of the battery. The bq2013H is designed for high cpaacity battery packs used in high-discharge rate sys- tems. Battery self-discharge is estimated based on an internal timer and tem- perature sensor. Compensations for battery temperature, rate of charge, and self-discharge are applied to the charge counter to provide available capacity information across a wide range of operating conditions. Initial battery capacity, self-discharge rate, display mode, and charge compensa- tion are set using the PROG1-6 pins. Actual battery capacity is automati- cally “learned” in the course of a dis- charge cycle from full to empty. Nominal available charge may be directly indicated using a five-seg- ment LED display. These segments are used to graphically indicate nominal available charge. The bq2013H supports a simple single-line bi-directional serial link to an external processor (common ground). The bq2013H outputs bat- tery information in response to exter- nal commands over the serial link. To support battery pack testing, the outputs may also be controlled by command. The external processor may also overwrite some of the bq2013H gas gauge data registers. The bq2013H may operate directly from four nickel cells or three lead acid. With the REF output and an external transistor, a simple, inexpen- sive regulator can be built to provide VCC from a greater number of cells. Internal registers include available charge, temperature, capacity, battery ID, and battery status.
