MCP73213-B6SI/MF

Battery Chargers Overview

The MCP73213-B6SI/MF is a linear battery charger controller designed for dual-cell lithium-ion or lithium-polymer batteries. It features an 8.2V output voltage and supports an input supply voltage range of 4.2V to 13V. The device delivers a programmable charging current between 130mA and 1.1A via an external resistor. Packaged in a DFN-10 (3x3mm) surface-mount format, it operates within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates overvoltage protection to prevent damage from input voltage spikes up to 18V.
• Employs constant-current/constant-voltage charging algorithm with thermal regulation to optimize cycle time.
• Offers flexible charging voltage adjustment options for diverse design requirements.
• Supports standby mode through high-impedance application on the PROG pin.

Battery Chargers Applications

• Portable electronic devices requiring compact power management solutions
• Applications utilizing low-cost wall adapters or prone to voltage transients
• Dual-cell lithium-ion or lithium-polymer battery systems

Battery Chargers Procurement Notes

Verify the specific suffix 'B6' against the official Microchip datasheet to confirm the exact output voltage configuration, as suffixes define functional parameters. Ensure the DFN-10 package dimensions align with PCB footprint requirements. Confirm that the selected programming resistor falls within the specified range for the desired charge current. Validate environmental ratings for the target operating conditions.

Battery Chargers Selection Notes

Select this component when designing for dual-cell Li-Ion/Li-Pol packs needing integrated overvoltage protection. It is suitable for space-constrained portable applications due to its small DFN-10 footprint. Choose based on the required 8.2V termination voltage and the need for thermal regulation during high-power charging. Consider the 130mA to 1.1A adjustable current range for system power budgeting.
