S-8261AAVBD-G2VTFG

Battery Management Overview

The S-8261AAVBD-G2VTFG is a battery protection IC for single-cell lithium-ion or lithium-polymer rechargeable batteries. It incorporates high-accuracy voltage detection circuits and delay circuits to protect against overcharge, overdischarge, and overcurrent conditions. The device utilizes internal high-voltage devices for charger connection pins, allowing an absolute maximum rating of 28 V. It features a three-step overcurrent detection circuit including load short-circuiting protection. An internal 0 V battery charge function is available, and the device includes a charger detection function that releases overdischarge hysteresis upon detecting negative voltage at the VM pin.

Battery Management Feature Summary

• Integrates high-accuracy voltage detection circuits with selectable thresholds for overcharge, overdischarge, and overcurrent protection.
• Features a three-step overcurrent detection system covering normal overcurrent, high-current faults, and load short-circuiting scenarios.
• Supports 0 V battery charging functionality and detects charger connection via negative voltage sensing at the VM pin.

Battery Management Applications

• Protection of single-cell lithium-ion battery packs
• Protection of single-cell lithium-polymer battery packs
• Portable electronic devices requiring integrated battery safety management

Battery Management Procurement Notes

Verify the specific suffix G2VTFG against official ABLIC documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required detection voltage steps and operating temperature range before integration. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity.

Battery Management Selection Notes

Select this component when designing protection circuits for single-cell Li-ion or Li-polymer batteries requiring integrated overcharge, overdischarge, and overcurrent safeguards. Consider the fixed overcurrent 2 detection voltage and the selectable parameters for other protection levels. Evaluate the need for 0 V charging capability and the benefit of internal delay generation without external capacitors.
