RT9460WSC

Overview

The RT9460WSC is a switch-mode single-cell Li-Ion/Li-Polymer battery charger IC designed for portable applications. It integrates a synchronous buck converter, power path management, and a linear LDO regulator to supply system loads. The device supports input voltages up to 5.5V and provides programmable charging current. It features an integrated thermal regulation loop to limit die temperature during high-power operation.

Feature Summary

• Integrates a synchronous buck converter with power path management for efficient charging and system load sharing.
• Includes an internal linear LDO regulator to provide stable voltage to the host system when the primary source is unavailable.
• Features automatic transition between charging modes based on battery temperature and input source status.

Applications

• Portable electronic devices requiring single-cell lithium battery charging
• Smartphones and mobile phones
• Personal digital assistants (PDAs)
• MP3 players and portable media devices

Procurement Notes
