Voltage Supervisors

Voltage supervisors, also called voltage monitors, voltage detectors, or reset ICs, are integrated circuits designed to monitor the voltage of a power supply rail. They provide a reset signal to a microcontroller or other digital system when the voltage falls outside a specified tolerance window. Voltage detectors play a critical role in ensuring reliable system operation by preventing the microcontroller from executing code with an unstable or incorrect power supply. This prevents unpredictable behaviour, data corruption, or even hardware damage. Essentially, they act as a safeguard against brownouts and power glitches.  

Why Choose Voltage Supervisors?

Choosing a voltage supervisor offers several key advantages. They enhance system reliability by preventing erratic operation due to power supply fluctuations. This is especially important in embedded systems and critical applications where stable performance is essential. Voltage supervisors also simplify the design process by providing a pre-built, tested solution for power supply monitoring, reducing the need for complex discrete circuitry. They offer a compact and cost-effective way to implement robust power management. Furthermore, they often include additional features like adjustable threshold voltages, watchdog timers, and power-on reset (POR) functionality, further streamlining the design and improving system robustness.

Types of Voltage Supervisors:

Voltage supervisors come in various configurations, each tailored to specific needs.  Some common types include:

  • Single-voltage supervisors: These monitor a single-voltage rail, typically the main supply voltage of the system.
  • Multi-voltage supervisors: These can monitor multiple voltage rails simultaneously, often used in systems with multiple power domains.  
  • Adjustable voltage supervisors: These allow the user to set the threshold voltage to trigger the reset, offering flexibility for different applications.
  • Supervisors with different output types: These can have open-drain, push-pull, or other output configurations to interface with different microcontroller reset inputs.  
  • Supervisors with integrated features: Some supervisors include additional features like watchdog timers, power-on reset (POR) functionality, or manual reset inputs.  

Typical Applications of Voltage Supervisors:

Voltage supervisors find wide application across various electronic systems, including:

  • Microcontroller-Based Systems
  • Embedded Systems
  • Automotive Electronics
  • Industrial Automation
  • Networking Equipment
  • Computer Systems.
