MAX712ESE+T

Battery Chargers Overview

The MAX712ESE+T is a fast-charge controller for NiCd and NiMH batteries, operating from a DC source at least 1.5V higher than the maximum battery voltage. It supports charging 1 to 16 series cells at rates up to 4C. Charge completion is determined by a voltage-slope detecting analog-to-digital converter, timer, and temperature window comparator. The device features a 5µA maximum drain on the battery when not charging and includes a 5V shunt regulator to power external logic.

Battery Chargers Feature Summary

• Supports fast-charging of 1 to 16 series NiCd or NiMH cells with flexible programming.
• Utilizes voltage-slope detection, temperature monitoring, and timer functions for precise charge termination.
• Automatically transitions from fast-charge to C/16 trickle-charge mode upon completion.

Battery Chargers Applications

• Laptop, notebook, and palmtop computers
• Handy-terminals and cellular phones
• Portable consumer products and cordless phones

Battery Chargers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the standard tube configuration found in other variants like MAX712ESE+. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability may vary. Ensure the component meets environmental regulations for the target market before finalizing procurement.

Battery Chargers Selection Notes

Select this component for applications requiring programmable fast-charge control for multi-cell NiCd or NiMH packs. It is suitable for designs needing linear or switch-mode power control options. Consider the 5V shunt regulator feature if external logic powering is required without additional components.

Battery Chargers Part Context

The MAX712 belongs to Maxim Integrated's family of battery management ICs designed for portable electronics. It addresses overcharge issues common in ordinary chargers by implementing advanced cutoff mechanisms. This part is specifically engineered to extend battery lifespan through safe, efficient charging profiles.

Battery Chargers Replacement Considerations

The MAX713 is a documented alternative within the same family, offering similar functionality for NiCd/NiMH fast-charge control. Verify pin compatibility and specific parameter tolerances before substitution.
