Description
General part information
BQ78412 Series
The bq78412 Pb-Acid Battery State-of-Charge (SoC) Indicator with Run-Time Display is a complete stand-alone battery gas-gauge solution designed for single 12V Pb-Acid batteries. The bq78412 displays remaining Run-Time-To-Empty during discharge and Percent (%) capacity during charge using a 10-LED (light-emitting diode) bar graph.
The bq78412 monitors battery voltage, current, and ambient temperature to calculate state-of-charge and determine remaining runtime-to-empty. Measured values can be recorded and tracked for later retrieval for warranty purposes.
Programmable cell models allow the bq78412 to be customized to a variety of Pb-Acid formulations and capacities.
