ISL6297CRZ-T

Battery Chargers Overview

The ISL6297CRZ-T is a single-cell lithium-ion/polymer battery charger IC manufactured by Renesas Electronics Corporation. It features a programmable constant-current charging mode with a maximum charge current of 1.1A and supports a battery pack voltage of 4.2V. The device operates within a supply voltage range of up to 6.5V and functions across an ambient temperature range of -20°C to 70°C. Packaged in a 16-VQFN (4x4mm) surface-mount housing with an exposed pad, it integrates timer-based programming for charge termination and includes fault protection mechanisms against over-temperature and over-voltage conditions.
