MCP73832T-2ATI/OT

Battery Chargers Overview

The MCP73832T-2ATI/OT is a fully integrated single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It operates within a supply voltage range of 3.75 V to 6 V and delivers a regulated output voltage of 4.2 V for the battery cell. The device supports a maximum programmable charging current of 500 mA and functions reliably across an operating temperature range of -40°C to +85°C. Housed in a compact SOT-23-5 surface-mount package, it provides complete control over the charging cycle.

Battery Chargers Feature Summary

• Fully integrated linear charge management controller designed for single-cell lithium-ion and lithium-polymer batteries
• Programmable constant-current charging capability with automatic termination upon reaching full charge
• Integrated thermal regulation to reduce charging current when die temperature reaches safety limits
• Status indicator pin provides visual feedback on charging activity and charge completion

Battery Chargers Applications

• Portable consumer electronics such as smartphones and digital cameras
• Medical devices requiring safe single-cell battery charging
• Industrial handheld instruments and sensors
• Personal navigation systems and GPS units

Battery Chargers Procurement Notes

Verify the specific suffix ATI against official Microchip documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with your PCB footprint for the SOT-23-5 package. Confirm that the 4.2 V output matches your battery specifications. Check for any recent product change notices regarding assembly sites or materials.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell Li-Ion or Li-Po charging is required. The 500 mA maximum current suits low-to-medium power applications. Consider the SOT-23-5 package size constraints. Verify that the input voltage source stays within the 3.75 V to 6 V operational range. Evaluate thermal requirements if high ambient temperatures are expected.
