SGM40565 - High Input Voltage Charger

General Description

The SGM40565 is a fully integrated high input voltage single-cell Li-Ion battery charger.

The charger deploys the CC/CV charging profile optimized for Li-Ion battery.

It charges at wide input voltage range (up to 26.5V), and adjusts charging current adaptively based on the die junction temperature.

Key Features

  • Integrated Pass Element and Current Sensor.
  • No External Blocking Diode Required.
  • Low Component Count and Cost.
  • Programmable Charge Current.
  • Programmable Full-of-Charge Current.
  • Charge Current Thermal Fold-Back for Thermal Protection.
  • 2.48V/2.55V/2.65V Trickle Charge Threshold.
  • 26.5V Maximum Voltage for the Power Input.
  • Power Presence and Charge Indications.
  • Less than 1μA Leakage Current off the Battery When No Input Power Attached or Charger Dis.

SGM40565 High Input Voltage Charger for Loosely Coupled Charging GENERAL DESCRIPTION The SGM40565 is a fully integrated high input voltage single-cell Li-Ion battery charger. The charger deploys the CC/CV charging profile optimized for Li-Ion battery. It charges at wide input voltage range (up to 26.5V), and adjusts charging current adaptively based on the die junction temperature. The charge current and the full-of-charge (FOC) current are programmable with external resistors. It safely precharges an over-discharged battery or a new battery with reduced charging current. The device also has LDO mode in which SGM40565 powers load with no battery installed, or maintains loading when battery is fully charged. 4.05V, 4.2V and 4.35V charging voltage options are available.
