MAX6783TEA+

Overview

The MAX6783TEA+ is a quad battery monitor from Analog Devices, designed for multi-chemistry applications. It provides high-accuracy voltage monitoring across four series-connected cells within a single integrated circuit. The device operates on a supply voltage ranging from 1.2 V to 5.5 V and supports reverse battery protection. It is housed in a compact 16-TQFN package with an exposed pad, suitable for space-constrained designs. The component functions reliably within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides accurate voltage measurement for up to four series-connected battery cells
• Supports monitoring of various multi-chemistry battery types
• Integrates reverse battery protection to safeguard the system
• Operates with low supply voltage requirements for efficient power management

Applications

• Industrial equipment requiring reliable multi-cell battery status tracking
• Portable medical devices needing precise energy level indication
• Embedded communication systems utilizing backup power sources
• Consumer electronics with complex battery pack architectures

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package integrity upon receipt as the TQFN-EP-16 requires careful handling. Check revision markings against official datasheets to ensure functional compatibility. Validate RoHS compliance documentation for regulatory adherence. Inspect leads and pads for corrosion before soldering.

Selection Notes

Choose this part when precise monitoring of four series cells is required without external multiplexers. Consider the 16-TQFN footprint for board space optimization. Ensure the application voltage stays within the 1.2 V to 5.5 V operational range. Evaluate thermal performance given the exposed pad design for heat dissipation needs.

Part Context

This component belongs to the MAX6783 family of battery monitors. It shares functional similarities with the MAX6782 but differs in packaging options. The TE suffix indicates a specific tape-and-reel or tube variant depending on the sub-model. It serves as a dedicated solution for cell balancing and state-of-health estimation in multi-cell stacks.

Replacement Considerations

The MAX6783TEB+ is a documented alternative within the same family. Verify pinout compatibility and package dimensions before substitution. Confirm that the replacement meets the same temperature and voltage specifications.
