Optimum Control to Maximize Battery Capacity  
and Life  
DESCRIPTION  
The bq24450 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. The versatile driver for the external pass transistor supports both NPN and PNP types  
and provides at least 25mA of base drive.  
In addition to the voltage- and current-regulating amplifiers, the IC features comparators that monitor the  
charging voltage and current. These comparators feed into an internal state machine that sequences the charge  
cycle. Some of these comparator outputs are made available as status signals at external pins of the IC. These  
status and control pins can be connected to a processor, or they can be connected up in flexible ways for  
standalone applications.
