Voltage supervisors and voltage references monitor system voltages to eliminate problems during operation. On power-down, the supervisor monitors the power supply voltage and resets the system if the voltage falls below a predetermined level. On power-up, the supervisor holds the system in reset until the voltage has stabilized.

Voltage (CPU) Supervisors

System and CPU supervisors and voltage detectors monitor system voltages to eliminate problems during operation. On power-down, the supervisor monitors the power supply voltage and resets the system if the voltage falls below a predetermined level. On power-up, the supervisor holds the system in reset until the voltage has stabilized.

Voltage References

We offer several families of series and shunt voltage references with options for high-accuracy, low-noise and general purpose use. These devices provide a stable reference for a wide variety of data conversion and signal conditioning applications.

Design Resources


MPLAB® Analog Designer

Provides design suggestions for common circuit needs, estimates performance for common modifications, and can export to MPLAB® Mindi™ Analog Simulator for verification.

MPLAB® Mindi™ Analog Simulator

Uses a SIMetrix/SIMPLIS environment to model circuit behavior, reducing design time with software debugging for initial design verification.

Power Check Design Service

Provides advice on your exact physical circuit layout, sharing best practices from an experienced power supply designer, so that physical hardware will match simulations.
