SC805IMLTRT

Overview

The SC805IMLTRT is a miniature integrated high-current lithium-ion battery charger manufactured by Semtech Corporation. It supports single-cell Li-ion and Li-polymer batteries, delivering a maximum charge current of 1A with an output voltage of 4.2V. The device operates within a supply voltage range of 2.85V to 5.5V and functions across a temperature range of -40°C to +85°C. Packaged in a 10-VFQFN exposed pad (MLP-10) for surface mount installation, it integrates thermal regulation and charge status indication.

Feature Summary

• Integrates high-current charging capability up to 1A for rapid power replenishment
• Includes automatic thermal regulation to manage heat dissipation during charging cycles
• Provides charge status indication through dedicated output pins

Applications

• Portable electronic devices requiring compact battery management
• Smartphones and mobile communication equipment
• Wearable technology and health monitoring devices

Procurement Notes

Verify component authenticity through authorized Semtech distributors or certified partners. Confirm the specific suffix matches the MLP-10 package configuration.
