MAX8730ETI+T

Battery Chargers Overview

The MAX8730ETI+T is a multi-chemistry battery charger IC manufactured by Analog Devices Inc./Maxim Integrated. It supports lead-acid, lithium-ion, nickel-cadmium, and nickel-metal hydride batteries with a maximum pack voltage of 17.6V and a supply voltage up to 28V. The device features a programmable constant-current charging capability with a maximum charge current of 4.5A. It operates within a temperature range of -40°C to +85°C and is housed in a 28-TQFN (5x5mm) package with an exposed pad.

Battery Chargers Feature Summary

• Supports multiple battery chemistries including lead-acid, Li-ion, NiCd, and NiMH
• Features programmable constant-current charging control
• Includes integrated overcurrent and short-circuit fault protection

Battery Chargers Applications

• Portable electronic devices requiring multi-chemistry battery support
• Industrial equipment utilizing lead-acid or NiMH battery packs
• Medical devices needing reliable multi-chemistry charging solutions

Battery Chargers Procurement Notes

Verify the exact suffix for tape-and-reel packaging, as the provided data references the tube variant. Confirm availability status directly with the manufacturer or authorized distributors due to potential lifecycle changes. Ensure the application circuit matches the specific battery chemistry selected for optimal performance and safety compliance.

Battery Chargers Selection Notes

Select this component when a single IC must handle diverse battery types without hardware changes. The 4.5A current rating suits medium-power applications. Verify that the system power supply can sustain the 28V input requirement. Consider thermal management requirements given the TQFN package size and power dissipation during high-current charging phases.

Battery Chargers Part Context

This part belongs to the Maxim Integrated battery charger family, designed for versatile power management in portable systems. It integrates charge termination logic and safety features typical of advanced PMICs from this series. The device simplifies design by supporting various chemistries through software configuration rather than external component changes.

Battery Chargers Replacement Considerations

Check for direct pin-compatible upgrades within the MAX873x series. Verify if newer generations offer improved efficiency or extended temperature ranges. Ensure any substitute maintains the 28V supply limit and 4.5A current capability.
