Description:

The KA35S28X series of battery charger controllers contain all of the necessary circuitry to optimally control the charge and hold cycle for sealed lead-acid batteries. These integrated circuits monitor and control both the output voltage and current of the charger through three separate charge states; a high current bulk-charge state, a controlled over-charge, and a precision float-charge, or standby, state.

Features:

• Optimum Control for Maximum Battery Capacity and Life

• Applicable to Various Types of Lead Battery

• Pin-Selectable Charge Algorithms (3 Step Voltage, Current, or Pulsed Charge)

• Automatically Shorted, Opened, or Damaged Cells Detections

• Automatically Battery Removal Detection

• Charge Condition LED Indicator Outputs (On, Pulsed, Off)

• Automatic Correction of Charging Current and Voltage Based on Current Temperature

• Maximum and Minimum Battery Temperature Protection

• Pre-Charge Qualification (Initial Trickle Charge for Deeply Discharged Batteries)

• Cycle/Float Button (For In-System Battery Charge Condition)

• Adjustable Charging Time Control by Changing the External Current Resistor

• Faster Charge Time Button

• Externally Disabling Charge Button

• Switch Mode Constant Current Generation

• Pb-Free (RoHS Compliant)

Applications:

• Handheld Equipment

• Portable Instruments and Communications

• Power Conditioning for Battery Systems

• Telecommunications

• Power Utility

• Emergency Lighting

• Control System

• Fire & Security
