ZM7308G-65502-T1

Overview

The ZM7308G-65502-T1 is a Digital Power Manager from the ZM7308G series, manufactured by Bel Power Solutions. It functions as a specialized power management IC designed to control and monitor up to 32 independent Z-series Point-of-Load (POL) converters via an industry-standard I2C interface. The device supports both 100kHz and 400kHz communication speeds and includes JTAG IEEE 1149.1 compliant programming capabilities. It features non-volatile memory for system configuration storage and user-accessible data, alongside hardware and software locks for protection.

Feature Summary

• Manages up to 32 independent Z-series POL converters through standard I2C and JTAG interfaces
• Provides flexible fault management with four independent OK lines and fast propagation support
• Includes non-volatile memory for storing system configuration and status data
• Supports AC Fail input and crowbar output for enhanced system protection

Applications

• Low voltage, high density systems utilizing Z-One Digital Intermediate Bus Architectures
• Broadband, networking, optical, and wireless communications systems
• Industrial computing, servers, and storage applications

Procurement Notes

Verify component authenticity against official Bel Power Solutions documentation due to limited availability. Confirm package integrity and pin alignment prior to integration. Check for RoHS compliance status in current manufacturing batches. Ensure compatibility with existing I2C bus configurations and voltage levels. Review datasheet revisions for any updates to pinout or electrical characteristics before finalizing design.

Selection Notes

Select this component for designs requiring centralized digital control of multiple POL converters. It is suitable for applications needing reduced board space and simplified power management architecture. Consider its I2C and JTAG interface requirements when designing host system connections. Evaluate the need for non-volatile memory retention and fault management features specific to the target application environment.
