产品概述

The LM3658SD-A/NOPB is a dual source USB/AC Li Chemistry Charger IC 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 50 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
  • Continuous battery temperature monitoring
  • Built-in multiple safety timers
  • Charge status indication
  • Continuous over-current and temperature protection
  • Near-depleted battery pre-conditioning
  • Sleep mode with ultra-low quiescent current
  • Onboard Kelvin-sensing achieves ±0.35% termination accuracy
  • Maintenance mode with automatic recharge
  • Green product and no Sb/Br
