Texas Instruments BQ2063
The bq2063 SBS-compliant gas gauge IC for battery-pack or in-system installation maintains an accurate record of available charge in Li-Ion batteries. The bq2063 monitors capacity and other critical parameters in Li-Ion battery packs. It also directly interfaces the Seiko S-8243 protection IC to minimize component count in smart-battery circuits.| Part No. | BQ2063 |

DESCRIPTION
CTL2−CTL4 9–11 O 3-state outputs to interface the S-8243 protection IC DISP 17 I Display control for the LED drivers LED1−LED5 ESCL 2 O Serial memory clock for data transfer between the bq2063 and the external nonvolatile configuration memory ESDA 3 I/O Bidirectional pin that transfers address and data to and from the bq2063 and the external nonvolatile configuration memory GND 24–25 Must be tied externally to VSS HDQ16 1 I/O Serial communication open-drain bidirectional communications port LED1−LED5 12–16 O LED display segments that each may drive an external LED RBI 4 I Register backup that provides backup potential to the bq2063 registers during periods of low operating voltage. RBI accepts a storage capacitor or a battery input REG 5 O Regular output to control an n-JFET for Vcc regulation to the bq2063 from the battery potential SAFETY 26 O Open-drain output for an additional level of safety protection (e.g., fuse blow) SMBC 28 I/O S
