PT8A2803ZEEX

Overview

The PT8A2803ZEEX is a single-cell lithium-ion or polymer battery charger integrated circuit manufactured by Diodes Incorporated. It provides a regulated charging current of 500mA and utilizes an 8-pin WFDFN package with an exposed pad for thermal management. The device supports standard charging profiles including pre-conditioning, constant current, and constant voltage stages with termination control.

Feature Summary

• Supports charging for single-cell lithium-ion and lithium-polymer batteries
• Integrates power MOSFETs to eliminate external sensing resistors and blocking diodes
• Includes automatic recharge functionality triggered when voltage drops below threshold

Applications

• Portable electronic devices requiring single-cell Li-ion/Polymer battery management
• Consumer electronics with limited board space constraints
• Battery-powered equipment utilizing USB or wall adapter power sources

Procurement Notes
