ISL6255HAZ-T

Battery Chargers Overview

The ISL6255HAZ-T is a highly integrated battery charger controller designed for notebook computers, manufactured by Renesas Electronics Corporation. It supports Lithium-ion and Lithium Polymer batteries with a maximum pack voltage of 17.64V. The device operates on a supply voltage ranging from 7V to 25V and delivers a programmable constant charge current up to 2.6A. It utilizes a synchronous buck topology for high efficiency and features a QFN-EP-28 package suitable for surface mount installation. The component functions within an operating temperature range of -10°C to +100°C.

Battery Chargers Feature Summary

• Implements a synchronous buck topology utilizing MOSFETs instead of diodes to select power sources and improve light load efficiency.
• Provides programmable constant output voltage accuracy of 0.5% over the operating temperature range.
• Integrates fault protection mechanisms including overtemperature and short circuit safeguards.

Battery Chargers Applications

• Battery charging systems for notebook computers
• Power management for portable electronic devices using Li-Ion or Li-Polymer cells

Battery Chargers Procurement Notes

Verify the specific suffix 'HAZ' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Confirm that the 'T' suffix indicates tape and reel packaging if required for assembly processes. Check current product lifecycle status as this series may be discontinued or subject to replacement notices.

Battery Chargers Selection Notes

Select this component when designing chargers for 2 to 4 series cell configurations requiring high efficiency in compact spaces. Ensure the input power supply voltage remains within the 7V to 25V operational window. Verify thermal management requirements for the QFN-EP-28 package given the 2.6A current capability and ambient temperature constraints.

Battery Chargers Part Context

This part belongs to the ISL6255 family of battery charger controllers. It is functionally related to other models like the ISL6253 but offers distinct pinout and integration levels tailored for modern notebook applications. The manufacturer transitioned from Intersil to Renesas Electronics during the product's lifecycle.
