MAX6327XR31

Overview

The MAX6327XR31+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features an active-high, push-pull reset output. The device monitors the input voltage against a fixed threshold of 3.08V with a typical accuracy of 2.5%. It provides a minimum reset pulse width of 100ms and consumes a maximum operating supply current of 1µA. The component is housed in a compact SC-70-3 package and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated portable equipment
• Active-high push-pull output configuration for direct logic interfacing
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring low standby current
• Microprocessor power supply monitoring systems
• Digital system voltage supervision

Procurement Notes

Verify the specific suffix designation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status through official documentation. Check current availability as distribution may vary. Ensure the selected part matches the required output polarity and reset timing specifications for the target application design.

Selection Notes

Select this component when an active-high reset signal is required for voltage supervision. Compare the fixed threshold against the system's nominal supply voltage to ensure proper triggering. Consider the SC-70-3 footprint constraints during layout. Evaluate the ultra-low quiescent current benefit for battery life optimization in portable applications.

Part Context

This device belongs to the MAX6327X series of microprocessor supervisory circuits. The series offers various threshold voltages and output configurations to accommodate different power supply standards. These circuits eliminate external components typically needed for power-on reset generation, simplifying the design of reliable digital systems.

Replacement Considerations

Cross-reference with other MAX6327 variants for different threshold voltages or output polarities. Verify pinout compatibility before substituting with similar supervisory ICs from other manufacturers.
