ISL88732HRTZ

Battery Chargers Overview

The ISL88732HRTZ is a lithium-ion battery charger IC designed for 1 to 4 series cells. It supports a maximum charging current of 8A and operates with a supply voltage up to 22V. The device features an I2C interface for programmability and includes overcurrent and overtemperature fault protection. It is housed in a 28-WFQFN package with exposed pad, suitable for surface mount installation.

Battery Chargers Feature Summary

• Supports constant current and pulse charging profiles for lithium-ion batteries
• Integrated I2C interface for digital control and monitoring
• Built-in protection against overcurrent and overtemperature conditions

Battery Chargers Applications

• Portable electronic devices requiring multi-cell battery management
• Industrial equipment with lithium-ion power systems
• Consumer electronics utilizing high-current charging requirements

Battery Chargers Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm package integrity and moisture sensitivity level handling procedures during storage and assembly. Ensure compatibility with existing I2C bus configurations and thermal design constraints before integration into final products.

Battery Chargers Selection Notes

Select this component for applications requiring precise control over 1-4 cell lithium-ion battery charging cycles. Consider the 28-QFN footprint and 22V max supply voltage limits when designing power stages. Evaluate thermal performance needs given the 8A capability and exposed pad requirement for heat dissipation.

Battery Chargers Part Context

Part of the Renesas ISL8873x family of battery chargers. Shares functional similarities with ISL88731 but differs in supply voltage specifications and specific feature sets. Designed for notebook and portable device battery management systems.

Battery Chargers Replacement Considerations

ISL88731HRZ serves as a related alternative within the same product family, though differences in supply voltage ratings (26V vs 22V) and specific protection features require careful evaluation before substitution.
