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.
The Pulse-Width Modulator (PWM) provides control for high-efficiency current and voltage
regulation. It allows the KA35S28X to control 3-step constant-voltage, constant current, or
pulsed-current charging. A charge cycle begins when power is applied or the battery is
replaced. For safety, charging is inhibited until the battery voltage is within configured limits.
If the battery voltage is less than the low-voltage threshold, the KA35S28X provides trickle-
current charging until the voltage rises into the allowed range. This procedure prevents high-
current charging of cells that are possibly damaged or reversed.
Charging is inhibited anytime if the temperature of the battery is outside the configurable,
allowed range. All voltage thresholds, in accordance with battery manufacturer's
recommendations, are change proportional to the temperature conditions.
KA35S28X can receive the types of charging algorithm or stop charging commands from its
mode selection pins. Also it can change the voltage thresholds when battery is connected to
an electronic circuit or raises charge speed by 25% only by individual pins that named as
"cycle/float" and "faster charge".
