Характеристики

LM3658SD/NOPBThe LM3658SD is a dual source USB/AC Li chemistry charger IC for portable applications. It can safely charge and maintain a single cell Li-ion/Polymer battery operating from an AC wall adapter or USB power source. Input power source selection of USB/AC is automatic. With both power sources present, the AC power source has priority. Charge current is programmed through an external resistor when operating from an AC wall adapter allowing charge currents from 50mA to 1000mA. When the battery is charged using USB power, charge currents of 100 or 500mA are pin-selectable. The termination voltage is controlled to within ±0.35% of 4.2V. The LM3658 requires few external components and integrates internal power FETs, reverse current protection and current sensing. The internal power FETs are thermally regulated to obtain the most efficient charging rate for a given ambient temperature.

• Integrated power FETs with thermal regulation
• Charges from either an AC wall adapter or USB power source with automatic source selection
• Continuous battery temperature monitoring
• Built-in multiple safety timers
• Charge status indication
• Continuous over-current and over-temperature protection
• Near-depleted battery pre-conditioning
• Sleep mode with ultra low quiescent current
• Maintenance mode with automatic recharge
• On-board Kelvin-sensing achieves ±0.35% termination accuracy
