Product Overview

The LTC4053EMSE-4.2#PBF is an USB compatible Lithium-Ion Battery Charger with thermal regulation. The IC contains an on-chip power MOSFET and eliminates the need for an external sense resistor and blocking diode. Thermal regulation automatically adjusts charge current to limit die temperature during high power or high ambient temperature conditions. This feature protects the end product and the LTC4053 from thermal stress while the IC charges the battery at maximum rate without interruption. The charge current and charge time can be set externally with a single resistor and capacitor, respectively. When the input supply (wall adapter or USB supply) is removed, the LTC4053 automatically enters a low current sleep mode, dropping the battery drain current to less than 5µA. The LTC4053 also includes NTC temperature sensing, C/10 detection circuitry, AC present logic, low battery charge conditioning (trickle charging) and shutdown (25µA supply current).
  • Charges single-cell Li-ion batteries directly from USB port
  • Thermal regulation maximizes charging rate without risk of overheating
  • Programmable charge current with 7% accuracy
  • Low dropout operation
  • No external MOSFET, sense resistor or blocking diode required
  • Programmable charge termination timer
  • Preset charge voltage with ±1% accuracy
  • C/10 charge current detection output
  • AC present logic output
  • 25µA Supply current in shutdown mode
  • Automatic recharge
  • Charge current monitor useful for gas gauging
  • Thermistor input for temperature qualified charging
