Overview
The MCP73834T-GPI/MF is a standalone linear Li-Ion/Li-Polymer charge management controller manufactured by Microchip Technology. It supports output voltages of 4.2 V, 4.35 V, 4.4 V, and 4.5 V with an output current capability of 1200 mA. The device operates on an input supply voltage ranging from 3.75 V to 6 V. It is housed in a 10-lead VFDFN package (3x3 mm) with an exposed pad, designed for surface-mount installation. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Standalone linear charge management controller architecture
- Supports lithium-ion and lithium-polymer battery chemistries
- Integrated thermal regulation for safe charging operations
Applications
- Portable electronic devices requiring single-cell lithium battery charging
- Consumer electronics utilizing Li-Ion or Li-Polymer power sources
- Battery management systems in compact mobile hardware
Procurement Notes
Verify the specific suffix 'GPI/MF' against official Microchip documentation to confirm package type and reel packaging details. Ensure compatibility with system input voltage ranges between 3.75 V and 6 V. Cross-reference thermal requirements for the 10-DFN exposed pad configuration during integration.
Selection Notes
Select this component for applications requiring a dedicated linear charger IC for single-cell lithium batteries. Consider the 1200 mA output current limit and the 10-DFN package dimensions for PCB layout constraints. Verify that the operating temperature range of -40°C to +85°C meets environmental specifications.
Part Context
This part belongs to the MCP73834 family of charge management controllers. It is distinct from variants like the MCP73834-FCI/UN which may use different packaging such as MSOP. The GPI/MF designation specifically indicates the 10-lead VFDFN package format used in this component.
Replacement Considerations
Direct substitutes include other MCP73834 variants with compatible pinouts and electrical characteristics, such as MCP73834-FCI/UN, provided the package difference is accounted for in the design.
