MCP73831T-3ACI/OT

Battery Chargers Overview

The MCP73831T-3ACI/OT is a Microchip Technology lithium-ion and lithium-polymer charge management controller designed for single-cell battery applications. It operates within a supply voltage range of 3.75 V to 6 V and delivers a fixed output charging voltage of 4.35 V. The device supports a maximum output current of 505 mA with programmable constant-current charging capabilities. Housed in a compact SOT-23-5 surface-mount package measuring 3.1 mm by 1.8 mm, it functions reliably across an industrial temperature range of -40 °C to +85 °C.

Battery Chargers Feature Summary

Fully integrated linear charge management controller optimized for space-limited designs
Supports both lithium-ion and lithium-polymer battery chemistries
Includes automatic recharge functionality triggered when battery voltage drops below threshold

Battery Chargers Applications

Portable electronic devices requiring single-cell lithium battery charging
Consumer electronics utilizing lithium-ion or lithium-polymer power sources
Compact hardware systems with strict PCB area constraints

Battery Chargers Procurement Notes

Verify the specific suffix '3ACI' confirms the 4.35 V fixed output voltage setting required for your design. Ensure the 'OT' designation matches your preferred tape-and-reel packaging format. Confirm that the SOT-23-5 footprint aligns with your board layout specifications before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when a fixed 4.35 V charging profile is necessary for the target battery chemistry. Consider the 505 mA maximum current limit against your system's power requirements. Evaluate the SOT-23-5 package dimensions against available board space compared to alternative packages like DFN.
