S-8240BAH-I6T1U

Battery Management Overview

The S-8240BAH-I6T1U is a battery protection IC designed for single-cell lithium-ion and lithium-polymer packs. It features high-accuracy voltage detection with an overcharge detection voltage of 4.35 V and accuracy of ±20 mV. The device operates within a supply voltage range of 1.5 V to 28 V and supports an operating temperature range of -40°C to +85°C. It is housed in an SNT-6A package.

Battery Management Feature Summary

• Integrates high-accuracy voltage detection circuits for precise cell monitoring
• Provides comprehensive protection against overcharge, overdischarge, and short-circuit conditions
• Supports low standby current consumption for extended battery life

Battery Management Applications

• Single-cell lithium-ion battery pack protection
• Lithium-polymer battery management systems
• Portable electronic devices requiring cell safety monitoring

Battery Management Procurement Notes

Verify the specific suffix I6T1U corresponds to the required tape-and-reel packaging configuration. Confirm that the 4.35 V overcharge detection threshold aligns with the target battery chemistry specifications. Ensure compatibility with the SNT-6A footprint during PCB layout validation.

Battery Management Selection Notes

Select this component when a fixed 4.35 V overcharge threshold is required. Compare against other series variants if different detection voltages or package types are needed. Verify that the 28 V maximum operating voltage meets the system's highest potential cell stack voltage.

Battery Management Part Context

This part belongs to the S-8240B series from ABLIC Inc., specialized for single-cell battery protection. It complements the broader S-8240 family by offering specific detection thresholds tailored for standard lithium-ion applications.

Battery Management Replacement Considerations

The S-8240AAH-I6T1U offers a similar function but with a different overcharge detection voltage (typically 4.25 V). Verify threshold requirements before substitution.
