G2241B - Switch mode Li-ion Battery Charger

This page provides the datasheet information for the G2241B, a member of the G2241B-GlobalMixed Switch mode Li-ion Battery Charger family.

Description

The G2241B provide a complete power supply solution.

They improve performance, component count, and size compared to other multi-channel controllers in 1-cell Li-Ion.

On-chip MOSFETs provide up to 92~95% efficiency for critical power supplies.

Features

  • 2.5V ~ 5.5V Input Voltage Operation.
  • 95% Efficient DC/DC Converter.
  • Built-in 4-ch synchronous buck converter, 5-ch LDOs, and 1-ch low quiescent current LDO for RTC.
  • Low Power consumption (Sleep Mode ) < 10µA.
  • Built-In Power ON/OFF Sequence for PMU.
  • Built-In Short Circuit Protection (SCP), Under Voltage Protection (UVP), and cycle-by cycle current limit for DC/DC Converters.
  • Integrated switched mode Li-ion charger with dynamic p.
