ISL9241HRTZ-T

Overview

The ISL9241HRTZ-T is a digital configurable buck-boost battery charger IC designed for 2 to 4-cell lithium-ion battery packs. It supports Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB) modes, with firmware-controlled switching between them. The device integrates system bus regulation and protection using only N-FETs, suitable for tablets, ultrabooks, and notebooks. It features an SMBus interface for configuration and monitoring.

Feature Summary

Supports NVDC and HPBB charging modes with firmware-controlled mode switching
Integrates system bus regulation and protection functions using external N-FETs
Features SMBus interface for digital configuration and status monitoring
Utilizes advanced R3 technology for high efficiency in light-load charging applications

Applications

Tablet computers
Ultrabook platforms
Notebook battery chargers

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm tape-and-reel packaging and quantity per reel. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through current datasheets. Validate that the ISL9241EVAL1Z development board is available for design verification if needed.

Selection Notes

Select this component for systems requiring flexible power path management between USB adapters and battery sources. It is appropriate for designs needing precise battery charging profiles managed via digital interfaces. Consider the 32-pin TQFN package constraints for thermal dissipation. Evaluate the need for external N-FETs to handle system load currents alongside the charger controller.

Part Context

The ISL9241 series belongs to Renesas' portfolio of battery management solutions for portable computing devices. It complements other models like the ISL9238 and ISL9538, offering similar SMBus-enabled control but tailored for specific input voltage ranges and cell configurations within the 2-4 cell lithium-ion ecosystem.

Replacement Considerations

Official substitutes include ISL9241HRTZ and ISL9241EVAL1Z for evaluation purposes. Cross-reference pinouts and electrical specifications with the latest Renesas datasheets before substitution.
