L-ASC10-1SG48I

Power Management - Specialized Overview

The L-ASC10-1SG48I is a hardware management expander from the Platform Manager 2 family, designed for power, thermal, and control plane monitoring. It features 10 voltage monitor inputs, 2 current monitor inputs, and 2 temperature monitor inputs. The device includes four MOSFET drivers and nine open-drain GPIOs compatible with 5V logic. Communication interfaces include I2C and JTAG. It operates within a supply voltage range of 2.8V to 3.6V and consumes 25mA of supply current.

Power Management - Specialized Feature Summary

• Provides independent hardware management submodules for power, temperature, and control planes to minimize cascade failures through nanosecond-level fault reaction times.
• Enables seamless scaling of system design by managing up to 80 power rails using minimal hardware expanders without requiring CPLD I/O pin resources for DC-DC converter power good signals.
• Offers reliable hardware-based power and temperature fault detection rather than relying on software judgment jump programs.

Power Management - Specialized Applications

• Hardware Management Expander
• Power Supply Voltage and Current Monitoring
• Temperature Monitoring
• Sequence and Margin Control

Power Management - Specialized Procurement Notes

Verify the specific ordering suffix '1SG48I' corresponds to the QFN-48 package and industrial temperature grade when sourcing. Confirm that the component status is listed as Active in official manufacturer catalogs to ensure long-term availability. Cross-reference the datasheet revision date against production timelines to ensure compatibility with current design specifications and regulatory requirements.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring scalable hardware management for multiple voltage rails and thermal nodes. It is suitable for applications needing fast, hardware-based fault detection to protect sensitive circuitry. Consider its integration with Platform Manager 2 controllers if centralized management of up to 80 power supplies is required while minimizing FPGA resource usage.

Power Management - Specialized Part Context

This part belongs to the Lattice L-ASC10 family, which serves as an analog sense and control expander. It complements the Platform Manager 2 series by providing dedicated monitoring capabilities for voltage, current, and temperature. The family aims to reduce BOM complexity by standardizing design across various systems without relying on single-function ICs from multiple suppliers.

Power Management - Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Lattice Semiconductor directly for cross-reference information or verify compatibility with alternative hardware management expanders based on specific interface and pinout requirements.
