BQ78412DDWR Description

Short technical summary and product information.

The BQ78412DDWR from Texas Instruments is a Gas Gauge IC specifically designed for single 12V Lead Acid batteries, commonly found in consumer UPS systems. This device functions as a Battery Monitor, providing critical data for charge status indication and runtime display.

 

Key specifications include a wide operating temperature range of -40°C to 85°C and a UART interface for configuration and data retrieval. It supports Lead Acid battery chemistry and is designed for 1 cell. The IC is housed in a 44-HTSSOP package and is surface-mountable.

 

This IC is capable of displaying remaining run-time during discharge and percentage capacity during charge using a 10-LED bar graph. It monitors battery voltage, current, and ambient temperature to calculate state-of-charge and remaining runtime. Measured values can be recorded internally for warranty purposes. Programmable cell models allow customization for various Pb-Acid formulations and capacities. The serial port can also support an optional infra-red interface for connector-less data acquisition.

 

Applications for the BQ78412DDWR include stand-alone uninterruptible power supplies, 12V Pb-Acid battery monitors, and battery warranty data logging equipment.
