SGM41527 - 1.6MHz Synchronous Li-Ion and Li-Polymer Stand-Alone Battery Chargers

Download the SGM41527 datasheet PDF. This datasheet also covers the SGM41526 variant, as both devices belong to the same 1.6mhz synchronous li-ion and li-polymer stand-alone battery chargers family and are provided as variant models within a single manufacturer datasheet.

Description

The SGM41526 and SGM41527 are stand-alone Li-Ion and Li-polymer battery chargers.

The PWM switches are integrated inside and they can automatically select the power path.

They also include gate drivers for external power path selector MOSFETs.

Features

  • 4A Synchronous 1.6MHz PWM Charger.
  • Cycle-by-Cycle Current Limit.
  • Integrated 24V Switching MOSFETs.
  • Integrated Bootstrap Diode.
  • Digital Soft-Start.
  • Up to 95.2% Charge Efficiency.
  • 30V Absolute Maximum Input Voltage Rating with Adjustable Over-Voltage Threshold.
  • 4.5V to 22V Input Operating Voltage Range.
  • Automatic Power Path Selector (Battery/Adapter).
  • Dynamic Power Management (DPM).
  • Battery Charge Voltage.
  • SGM41526: Select 2-, 3-, or 4-C.
