ISL6297CRZ

Battery Chargers Overview

The ISL6297CRZ is a single-cell lithium-ion/polymer battery charger IC manufactured by Renesas Electronics Corporation. It features a programmable constant-current charging capability with a maximum charge current of 1.1A. The device supports a battery pack voltage of 4.2V and operates within an input supply voltage range up to 6.5V. Designed for surface-mount installation, it utilizes a 16-VQFN package with an exposed pad (4x4 mm). The component functions across a temperature range of -20°C to +70°C and includes fault protection mechanisms such as over-temperature and over-voltage safeguards.

Battery Chargers Procurement Notes

Verify the exact suffix designation, as the requested model includes a 'Z' suffix indicating RoHS compliance, whereas source data references the non-RoHS 'ISL6297CR'. Confirm availability status, as the base part number is listed as obsolete in official records. Ensure compatibility with existing PCB footprints for the 16-QFN package before procurement.

Battery Chargers Selection Notes

Select this component for applications requiring a compact, single-cell charging solution with integrated thermal management. Consider the 1.1A maximum current limit and 4.2V output specification when designing the power stage. Verify that the operating temperature range meets the environmental requirements of the target application.
