bq29312 - 3- and 4-Cell Lithium-Ion or Lithium-Polymer Battery Protection

Description

The bq29312 is a 2-, 3-, or 4-cell lithium-ion battery pack protection analog front end (AFE) IC that incorporates a 3.3-V, 25-mA low-dropout regulator (LDO).

The bq29312 also integrates an I2C compatible interface to extract battery parameters such as cell voltages and control output status.

Features

  • 2-, 3-, or 4-Cell Series Protection Control.
  • Can Directly Interface With the bq2084 Gas Gauges.
  • Provides Individual Cell Voltages and Battery Voltage to Battery Management Host.
  • Integrated Cell Balancing Drive.
  • I2C Compatible User Interface Allows Access to Battery Information.
  • Programmable Threshold and Delay for Over Load and Short Circuit During Charge and Discharge.
  • System Alert Interrupt Output.
  • Host Control Can Initia.
