Texas Instruments bq2016
The bq2016 gas gauge IC for battery pack or in-system installation maintains an accurate record of available battery capacity. The bq2016 compensates for battery temperature, charge/discharge rate, and battery self-discharge to the charge counter to provide availablecapacity information across a wide range of operating conditions. The bq2016 works with NiCd or NiMH battery packs that have a capacity of 1 to 4.5 Ah and that are designed for high discharge rate applications such as power tools.| Part No. | bq2016 |

DESCRIPTION
HDQ 1 I/O Serial communication input/output. Open-drain bidirectional communications port. RBI 4 I Register backup input provides backup potential to the bq2016 registers during periods of low operating voltage. RBI accepts a storage capacitor or a battery input. REG 5 O Regulator output provides a reference to control an n-JFET for VCC regulation to the bq2016 from the battery potential. VCC VSS LED1–LED5 7 8 10–14 I Supply voltage input Ground O LED display segment outputs that each may drive an external LED. CVON 17 O Cell voltage divider control. Output to connect the voltage divider on the voltage input during measurement. VPFC 24 I Program capacity input. 16-level input to program the initial battery full-charge reference. SB 26 I Battery voltage input. Input connection to monitor battery–pack voltage. SR2–SR1 21,22 I Sense resistor inputs. Input connections for a small value sense resistor to monitor the battery charge and discharge current flow. SRC 20 I Current sense voltage input to monitor instantaneous current.
