MAX810STRG

Supervisors Overview

The MAX810STRG is a microprocessor supervisory circuit manufactured by onsemi, designed to monitor power supply voltages in digital systems. It provides a reset signal to the host processor when necessary, eliminating the need for external components. The device features a push-pull active-high output and operates within a specified voltage range with low supply current consumption. It is housed in a compact SOT-23-3 package suitable for surface-mount applications.

Supervisors Feature Summary

• Monitors system power supplies to ensure reliable operation of microprocessors and digital circuits
• Provides a guaranteed reset signal upon power-up or voltage threshold crossing without external adjustments
• Features a push-pull output configuration for robust drive capability
• Operates with minimal supply current to support battery-powered applications

Supervisors Applications

• Microprocessor and microcontroller power monitoring
• Portable and battery-powered equipment
• Automotive electronic systems
• Industrial controllers and intelligent instruments

Supervisors Procurement Notes

Verify the manufacturer designation carefully, as the MAX810 series was originally developed by Maxim Integrated, which is now part of Analog Devices. Ensure the supplier is an authorized distributor for onsemi or Analog Devices products to guarantee authenticity. Confirm that the specific suffix STRG corresponds to the desired package and tape-and-reel configuration for your manufacturing process.

Supervisors Selection Notes

Select this component when a cost-effective, single-channel supervisor with a push-pull output is required. It is suitable for systems powered by +5V, +3.3V, +3.0V, or +2.5V rails. Consider the fixed threshold voltage and timeout period specifications against your system's timing requirements. The SOT-23-3 package offers a small footprint for space-constrained designs.

Supervisors Part Context

The MAX810 belongs to a family of microprocessor reset monitors that includes variants like the MAX803 and MAX809. These devices are widely used in embedded systems to prevent erratic behavior during power transitions. The MAX810 specifically distinguishes itself with its push-pull output stage, offering better noise immunity and drive strength compared to open-drain alternatives.

Supervisors Replacement Considerations

Compatible substitutes include the MAX809 (open-drain output) and MAX803 (open-drain output) from the same family. Cross-reference with CAT810 series parts from other manufacturers if pin compatibility and threshold voltages match. Verify that any replacement maintains the same output configuration and electrical characteristics.
