MCP73213T-B6AI/MF

Battery Chargers Overview

The MCP73213T-B6AI/MF is a linear battery charger controller designed for dual-cell lithium-ion or lithium-polymer batteries. It features an integrated charge termination timer and operates with a supply voltage range of 4.2 V to 13 V. The device supports a programmable constant current charging rate from 130 mA to 1.1 A via an external resistor. It provides a fixed output voltage of 8.2 V for the series-connected battery pack. Thermal regulation automatically reduces the charging current when die temperature limits are reached, ensuring safe operation in high-power or high-ambient temperature environments.

Battery Chargers Feature Summary

• Integrates a dedicated charge termination timer to eliminate the need for external monitoring circuitry.
• Provides automatic thermal regulation that adjusts charging current based on junction temperature.
• Supports flexible input power sources including low-cost wall adapters and USB ports.
• Features a PROG pin that functions as both current programming and device enable control.

Battery Chargers Applications

• Portable electronic devices requiring dual-cell battery management
• Consumer electronics powered by lithium-ion or lithium-polymer packs
• Industrial handheld equipment operating in variable thermal conditions

Battery Chargers Procurement Notes

Verify the specific suffix 'B6AI' against the manufacturer's official datasheet to confirm the exact output voltage tolerance and package variant. Ensure the ordering part number matches the required reel quantity specifications. Cross-reference the component marking code with Microchip documentation to prevent counterfeit substitution errors during assembly.

Battery Chargers Selection Notes

Select this controller for applications requiring a compact solution for two-series cell batteries. The DFN-10 package offers a small footprint suitable for space-constrained designs. Consider the thermal performance requirements if operating near the maximum ambient temperature limit. Verify that the external programming resistor allows for the desired charging current within the specified operational range.

Battery Chargers Part Context

This component belongs to the MCP73213 family of battery chargers. Variants within this series differ primarily in output voltage settings and package configurations. The T suffix indicates tape-and-reel packaging for automated surface-mount assembly. Other members may support single-cell configurations or different voltage thresholds.
