Active Decoupling / Switched-Cap Arrays One-line scope: Active decouplers and switched-cap arrays that dynamically lower PDN impedance to suppress droop and ringing during load transients.

Active EMI Filters & CM/DM Helpers One-line scope: Active EMI front-ends and common/differential-mode helpers that reduce EMI envelope peaks and relax output capacitor budgets.

Calibration & Production Test Helpers One-line scope: Reference sources and switch matrices for line calibration of V/I/T, enabling repeatable PI validation and traceability.

Current Sense Amplifiers & Shunt Monitors One-line scope: High-accuracy shunt monitors with wide common-mode range, power calculation, and alarms for fast-changing loads.

Ground Bounce & Rail Ripple Monitors One-line scope: Monitors that observe return-path noise, ground bounce, and rail ripple peaks/spectra to trigger protection or drive decoupling fixes.

Glitch Filters & Window Detectors One-line scope: Time-constant filtering and window comparators to reject narrow glitches and certify “voltage ready” windows.

Hold-Up & Backup Rail Managers One-line scope: Supercap/backup rail controllers for ride-through, event logging, and coordinated PG/sequence handling during interruptions.

Hot-Swap & eFuse with Telemetry One-line scope: Inrush control, current limiting, and fast disconnect with I²C/PMBus telemetry and programmable SOA protections.

On-Board Power Metering One-line scope: Energy/efficiency metering per rail/domain to profile loads and guide PDN and DVFS table optimization.

PMBus/SMBus Power System Managers One-line scope: Multi-rail managers for sequencing, fault trees, black-box logging, and centralized telemetry orchestration.

PG Aggregators & Voters One-line scope: AND/OR/majority voting of multiple PG/alert lines to simplify upper-layer timing and interlocks.

Power Bus Isolators & Protection Helpers One-line scope: Isolated digital power interfaces and telemetry with UVLO, reverse polarity/backfeed protection, and controlled startup.

Power Health Loggers & Black-Box Recorders One-line scope: Event recorders for OV/UV/OC/OT sequences, enabling post-mortem analysis even after power loss.

Power Monitors with ADC One-line scope: Single-/multi-channel voltage/current/power monitors with thresholds and bus readout for telemetry and protection.

Power Sequencers & Reset Managers One-line scope: 3–20+ rail up/down sequencing, interlocks, and fault tolerance, producing consolidated PG logic.

Remote Power Monitors (Satellite Nodes) One-line scope: Small monitoring nodes for remote boards/zones, returning V/I/T and alerts via I²C/PMBus.

Remote Sense / Kelvin Sense Amplifiers One-line scope: Low-offset differential amplifiers for precise remote VOUT sampling and compensation across long traces or interconnects.

Sense MUX & Probe Switches for PI One-line scope: Multiplexed sense/probe switching for multi-point V/I/T measurements, with calibration alignment and reduced probe intrusion.

Spread-Spectrum & Noise Shaping Helpers One-line scope: Modulation helpers that spread switching noise energy to reduce EMI peaks and ease compliance.

Telemetry Aggregators & Hubs One-line scope: Aggregation of V/I/T/status registers from multiple PMICs/PoLs with unified timestamps and bandwidth control.

Thermal Sensors for PI One-line scope: Multi-point thermal sensing (with digital interfaces/alerts) to catch hotspots in inductors and power devices.

Timing Aligners for Telemetry & PG One-line scope: Align PG, telemetry, and PLL/clock events to a common cadence for DVFS and validation evidence.

Transient Shaping & Load-Line Modulators One-line scope: AVP/dynamic load-line helpers that control undershoot and accelerate recovery during transients.

Trigger Bridges: GPIO↔PMBus One-line scope: Bridges between fast hardware triggers/interlocks and PMBus software commands, enabling safe dual-path control.

Voltage Margining DACs One-line scope: External DACs for ±margining, production calibration, and aging compensation of PMIC/PoL outputs; supports scripted sweeps.
