Product Summary

The BQ2012SN-D107TR is a Gas Gauge IC With Slow-Charge Control intended for battery-pack or in-system installation to maintain an accurate record of available battery charge. The BQ2012SN-D107TR 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 sensor.

Parametrics

BQ2012SN-D107TR absolute maximum ratings: (1)VCC Relative to VSS: -0.3 7.0 V; (2)All other pins Relative to VSS: -0.3 7.0 V; (3)REF Relative to VSS: -0.3 8.5 V; (4)VSR Relative to VSS: -0.3 7.0 V; (5)TOPR, Operating temperature: 0 to 70℃.

Features

BQ2012SN-D107TR features: (1)Conservative and repeatable measurement of available charge in rechargeable batteries; (2)Charge control output; (3)Designed for battery pack integration, 120μA typical standby current (self-discharge estimation mode); Small size enables implementations in as little as 1/2 square inch of PCB; (4)Integrate within a system or as a stand-alone device, Display capacity via singlewire serial communication port or direct drive of LEDs; (5)Measurements compensated for current and temperature; (6)Self-discharge compensation using internal temperature sensor; (7)16-pin narrow SOIC.
