MCP73213-A6BI/MF

Battery Chargers Overview

The MCP73213-A6BI/MF is a highly integrated linear battery charger controller designed for lithium-ion and lithium-polymer batteries. It supports dual-cell configurations with an output voltage of 9.2 V and a maximum output current of 1.1 A. The device operates within a supply voltage range of 4.0 V to 13 V and functions across an industrial temperature range of -40 °C to +85 °C. Packaged in a 10-pin VFDFN exposed pad (3x3 mm) suitable for surface mount installation, it utilizes a constant-current/constant-voltage algorithm. Thermal regulation limits charging current based on die temperature to ensure reliability.

Battery Chargers Feature Summary

• Integrates thermal regulation to limit charging current during high-power or high-temperature conditions
• Supports programmable charge current via a single external resistor
• Features undervoltage lockout and overvoltage protection for the input supply
• Includes status indicators for charge completion and fault detection

Battery Chargers Applications

• Portable electronic devices requiring space-constrained power management
• Dual-cell lithium-ion or lithium-polymer battery packs
• Cost-sensitive consumer electronics applications
• Industrial equipment operating in wide temperature environments

Battery Chargers Procurement Notes

Verify the specific suffix 'A6BI' against the manufacturer's official datasheet to confirm the exact output voltage tolerance and package marking code. Ensure the procurement source provides valid Microchip Technology documentation. Confirm that the 10-pin VFDFN footprint matches the design requirements. Check for any RoHS compliance declarations if required by the target market regulations.

Battery Chargers Selection Notes

Select this component when designing for dual-cell Li-Ion/Li-Po systems requiring up to 1.1 A charging current. The fixed 9.2 V output voltage suits series-connected two-cell configurations. Consider the exposed pad thermal performance for high-current applications. Verify that the input supply voltage remains within the 4.0 V to 13 V operational window to prevent undervoltage lockout or damage.

Battery Chargers Part Context

This part belongs to the MCP73213 family of battery charge management controllers from Microchip Technology. The family offers various output voltage options and current ratings tailored for different cell configurations. The MCP73213 series is characterized by its high integration level, reducing external component count compared to discrete solutions. It targets applications where board space and bill-of-materials cost are critical constraints.

Battery Chargers Replacement Considerations

Compatible substitutes include other variants within the MCP73213 family, such as MCP73213-B6SI/MF or MCP73213-G6XI/MF, provided their output voltages match the system requirements. Cross-reference pinouts and thermal characteristics before substitution.
