Pin Configuration

Characteristics

• Offers high-efficiency battery charging over a wide voltage range
  • with accurate and programmable charge current and charge voltage regulation
• Pulse Frequency Modulation(PFM) available while switching under light-load the device for more efficiency
• Device checks battery voltage and charges in different phases
  • Trickle Charging
    • Charging fully charge battery at a rate equal to its self-discharge
  • Pre-Charging
    • Small current to make it slowly reactive
    • Typical 1/10 of constant current charging
  • Constant Current Charging
    • 80% of battery’s state of charge at fastest rate
  • Constant Voltage Charging
    • Voltage held constant to prevent damage
    • Helps with non-overcharging

• At end of charging cycle, charger automatically terminates when charge current is below termination current limit in constant voltage phases
