Product Overview: MAX6376XR31+T from Maxim Integrated

The MAX6376XR31+T is a precision, low-power, low-voltage microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring nominal system voltages from 1.8V to 5.0V. This component is part of Maxim Integrated's extensive range of power management and supervisory circuits, known for their high quality and reliability.

This supervisory circuit is specifically designed to maintain system integrity by monitoring the power supply voltage levels. It asserts a reset signal whenever the VCC supply voltage falls below its factory-set reset threshold. The reset signal remains asserted for a preset timeout period after VCC has risen above the reset threshold, ensuring that the system has stabilized before the processor is allowed to run.

The MAX6376XR31+T operates with a very low quiescent current of only 1.6µA, which is ideal for portable and battery-powered applications where power conservation is critical. It supports a reset threshold voltage of 3.08V, which is suitable for 3.3V powered systems.

Key features of the MAX6376XR31+T include:

• Factory-Set Reset Threshold Voltages for 3.3V Systems
• Low 1.6µA Supply Current
• Guaranteed Reset Valid to VCC = 1V
• 140ms min Reset Timeout Period
• Push-Pull Active-Low Reset Output
• Immune to Short VCC Transients
• Small 3-Pin SOT23 Package

The device comes in a small 3-pin SOT23 package, making it easy to incorporate into space-constrained designs. Its push-pull active-low reset output ensures compatibility with most microprocessors and digital systems, providing a straightforward interface for system reset and power management.

The MAX6376XR31+T is versatile and can be used in a variety of applications, including portable devices, embedded systems, computers, and any other systems that require a reliable reset mechanism to safeguard against power supply glitches and brownouts.

Maxim Integrated's commitment to quality ensures that the MAX6376XR31+T supervisory circuit is a dependable choice for designers looking to enhance system reliability and performance while maintaining cost-effectiveness.
