ISL6253HAZ

Battery Chargers Overview

The ISL6253HAZ is a highly integrated battery charger controller designed for notebook computers, manufactured by Renesas Electronics Corporation. It supports Li-Ion and Li-Polymer batteries using a synchronous buck topology with MOSFET-based power selection. The device features current-mode control and adjustable thresholds. It is housed in a 28-pin SSOP package (PDSO28) with lead-free plastic construction. The component operates as a single-channel power supply support circuit.

Battery Chargers Feature Summary

• Synchronous buck topology utilizing MOSFETs for high efficiency power selection from adapter or battery sources
• Light load efficiency optimization through low-side MOSFET diode emulation to prevent system bus boosting
• Adjustable output voltage thresholds supporting configurations for two, three, or four series Li-Ion cells

Battery Chargers Applications

• Notebook computer battery charging systems
• Li-Ion battery management circuits
• Li-Polymer battery charging applications

Battery Chargers Procurement Notes

Verify the specific package designation upon ordering, as datasheets may list both SSOP-28 and QFN-28 variants under similar part numbers. Confirm RoHS compliance status and lead-free specifications match project requirements. Cross-reference the manufacturer's latest documentation to ensure the exact suffix corresponds to the desired physical footprint and pinout configuration before finalizing procurement.

Battery Chargers Selection Notes

Select this component for applications requiring a single-channel solution for notebook battery packs. Ensure the design accommodates the synchronous buck architecture and external MOSFETs. Verify that the required number of series cells aligns with the adjustable threshold capabilities. Consider thermal performance within the SSOP package constraints for the intended operating environment.
