Overview
The MCP73861T-I/SLG is a highly integrated single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It operates within an industrial temperature range and supports charging currents up to 1200 mA with programmable termination thresholds of 4.1 V or 4.2 V. The device utilizes a 16-pin SOIC-N package in tape-and-reel configuration, designed for space-constrained applications requiring efficient power management.
Feature Summary
- Highly integrated linear solution for system load distribution and battery charging
- Supports both lithium-ion and lithium-polymer battery chemistries
- Programmable charge termination voltage options for specific cell requirements
Applications
- Portable electronic devices with limited board space
- Battery-powered consumer electronics
- Industrial control systems requiring reliable single-cell charging
Procurement Notes
Verify the exact suffix against official Microchip documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may list discontinued or limited-stock items. Ensure the ordering part number matches the required termination voltage specification before procurement.
Selection Notes
Select this component when a compact, single-chip solution is needed for Li-ion or Li-Po cells. Consider the 16-pin SOIC-N footprint for PCB layout constraints. Verify that the required charge current and termination voltage align with the device's programmable capabilities and thermal dissipation limits.
Part Context
This part belongs to the MCP73xx series of charge management controllers from Microchip Technology. The series is characterized by high integration levels suitable for space-limited designs. The 'T' indicates tape-and-reel packaging, while 'I' denotes the industrial temperature range classification.
Replacement Considerations
