STPM098-TR

Overview

The STPM098-TR is an automotive-grade, dual-loop digital multi-phase buck controller featuring an embedded ARM Cortex-M0+ CPU and non-volatile memory. It supports up to eight external drivers for high-power load management, such as processor cores. The device utilizes a constant on-time control scheme for fast transient response and efficiency. It includes dynamic phase shedding, phase interleaving, and active diode emulation. Communication is handled via PMBus rev 1.2 with configurable telemetry and fault protection.

Feature Summary

• Dual-loop architecture supporting flexible phase assignment configurations for independent voltage regulation
• Embedded ARM Cortex-M0+ processor enabling advanced digital control and programmable parameters stored in NVM
• Comprehensive fault protection including overcurrent, undervoltage, overvoltage, and feedback disconnection diagnostics
• PMBus interface support for real-time telemetry monitoring of voltage, current, power, and temperature

Applications

• Power management for automotive processor cores
• High-power memory subsystem supply
• Automotive electronic control units requiring ASIL-D compliance

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm AEC-Q100 qualification status and ISO26262 compliance requirements for your target application. Ensure compatibility with PMBus version 1.2 protocols during system integration. Check for any specific ordering restrictions or regional availability constraints directly with the manufacturer.

Selection Notes
