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
• Renewables
• UPS
