Sentinel Power is a product line that includes power signature monitoring sensors, prognostic reasoners, and a visualization tool. It is part of the Sentinel Suite family of prognostic and health management (PHM) solutions.
Power systems may wear out and cause catastrophic failures in the system they are designed to enable. Fortunately, even as a power system is still performing within nominal limits, it may exhibit tell-tale signs of degradation. Such signatures are extracted and processed by Sentinel Power in order to provide advance warning of impending failure, actionable maintenance data to help eliminate system disruption while also avoiding unnecessary maintenance events.
Sensors
SMRT Probe 4000™: The Sentinel Power product line features the SMRT Probe 4000 . This sensor, based on Ridgetop’s patented RingDown™ technology, provides the signature waveforms necessary for advanced diagnostics and prognostics for power systems. As a “smart sensor”, it generates data that can be immediately processed for PHM analysis without any further data conditioning or filtering.
Reasoners
ARULE™: Ridgetop’s patented Adaptive Remaining Useful LIfe Estimator™ (ARULE) calculates a system’s state of health (SoH) and remaining useful life (RUL). It accepts waveform data directly from SMRT Probe sensors or, with a customized Sentinel Power data conditioner, from other suitable sensors.
Visualization
Sentinel PowerView™: PowerView is a visualization tool to display data collected by the sensor and to monitor changes in performance.
Applications
Together the Sentinel Power line can help you reduce the cost of maintenance for a wide range of applications, including:
- Power converters and inverters
- Power supplies
- Electronic drivers and stages
- Heating elements, such as those of aerospace total air temperature (TAT ) probes
Product Configuration
Sentinel Power product line includes the Sentinel Power Development Kit, for creating new applications using Sentinel Power technology, as well as the individual products mentioned above: SMRT Probe 4000, ARULE, and Sentinel PowerView.

Ridgetop is certified as category 1A under the Defense Microelectronics Activity (DMEA) as part of the Trusted Supplier Program. Ridgetop has history of designing analog and mixed signal ICs for demanding applications in space satellites that are subjected to extreme temperatures and radiation. Our designs have utilized bulk CMOS, CMOS-SOI, and SiGe at process geometries down to 28 nm channel lengths. Radiation hardness is also a concern, and Ridgetop has addressed those requirements as well. A recent Ridgetop design was delivered to ON Semiconductor for the U.S. Air Force STELLAR Star Tracker.
Under contract to NASA, Ridgetop designed an effective 3-axis wireless rotational sensor. The RotoSense™ sensor has been tested on fast-spinning pinion gears on helicopter gear boxes, and also rolling stock for railroad safety improvements.
