ACT8846QM460-T

Overview

The ACT8846QM460-T is a specialized Power Management IC (PMIC) manufactured by Qorvo, designed as an advanced PMU for multi-core application processors. It operates within an input voltage range of 3 V to 5.5 V and features a TQFN-48 surface-mount package. The device provides multiple output currents including 150 mA, 350 mA, 1.5 A, and 2.8 A, with maximum and output voltage ranges up to 3.3 V and 1 V to 3.3 V respectively. It functions at a working supply voltage of 3.6 V with an input current of 600 uA, supporting temperatures from -40°C to +85°C.

Feature Summary

• Advanced power management unit architecture tailored for complex multi-core processor systems
• Integrated switching regulator and linear regulator capabilities within a single compact package
• Supports surface-mount installation in high-density electronic designs

Applications

• Multi-core application processors
• Complex system-on-chip power distribution
• High-performance embedded computing platforms

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm RoHS compliance details prior to integration. Ensure storage conditions account for humidity sensitivity requirements. Validate package integrity upon receipt to prevent damage to the TQFN-48 leads. Cross-reference ordering suffixes to ensure exact functional matching with design specifications.

Selection Notes

Select this component when designing power architectures for multi-core processors requiring integrated buck and LDO solutions. Consider the TQFN-48 footprint for PCB layout constraints. Evaluate thermal performance within the specified operating temperature range. Verify that the input voltage range aligns with the system's primary power source. Assess current delivery capabilities against processor rail requirements.

Part Context

This part belongs to the ACT8846 series of specialized PMICs from Qorvo. It is distinct from development tools like the ACT8846EVK1-460 or evaluation kits such as the EA8846. The model represents a production-grade integrated circuit rather than a testing accessory, focusing on delivering stable power rails for advanced processing units.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for potential obsolescence management or cross-reference options.
