Typical Application Circuit

Applications

• Power Tools
• Wireless Speakers
• Mobile Printers

Design Notes

• Charge current accuracy depends on the sense resistor tolerance, so use a 1% or better part and keep its traces Kelvin-connected.
• Wire the NTC input for JEITA profile control if the pack is charged over temperature.
• Set the input current limit to what the adapter can actually deliver; a limit above the adapter rating causes the input rail to collapse mid-charge.
• Termination current and recharge threshold dominate cycle life in shallow-cycling products.
