Product Description

The BQ24450DW is an Integrated-charge Controller for lead-acid batteries contains all the necessary circuitry to optimally control the charging of valve-regulated lead-acid batteries. The IC controls the charging current as well as the charging voltage to safely and efficiently charge the battery, maximizing battery capacity and life. Depending on the application, the IC can be configured as a simple constant-voltage float charge controller or a dual-voltage float-cum-boost charge controller. The built-in precision voltage reference is especially temperature-compensated to track the characteristics of lead-acid cells and maintains optimum charging voltage over an extended temperature range without using any external components. The ICs low current consumption allows for accurate temperature monitoring by minimizing self-heating effects. The IC can support a wide range of battery capacities and charging currents, limited only by the selection of the external pass transistor.
Regulates both voltage and current during charging
Maximizes battery capacity over-temperature
Ensures safety while charging over-temperature
Optimum control to maximize battery capacity and life
Supports different configurations
Minimum external components
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
