Product Overview

The MAX1736EUT42+T is a single-cell Li+ battery charger for current limited supply in 6 pin SOT-23 package. It provides simple, safe, low cost method of charging single-cell Li+ battery with nearly no heat generation. Combined with current limited voltage source IC provides precharge, fast-charge and top-off-charge capabilities. After constant current fast charge, top-off safely finishes charging battery by pulse width modulating charge current. The top-off on-time is kept below electrochemical time constant of cell. The key advantage of this method is charge circuit is small and generates minimal heat while providing a safe method of charging to ensure maximum cell life. It initiates charging in one of four ways, battery insertion, charger power-up, battery voltage threshold and by external manipulation of the EN pin. It is used in single-cell Li+ portable applications, wireless handsets, personal digital assistants, digital cameras, self-charging battery packs and cradle chargers.
  • Input voltage range is 4.7V to 22V
  • Operating temperature range from -40°C to 85°C
  • Stand-alone or µP-controlled operation
  • 0.5% voltage set-point accuracy
  • Lowest power dissipation
  • Low 4.7V min input voltage
  • Top-off charging to achieve full battery capacity
  • No inductor required
  • Safely pre-charges near dead cells
  • Automatic power down when input power removed
