MAX6326XR30

Supervisors Overview

The MAX6326XR30 is a voltage supervisory circuit from the MAX6326U series, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 3.0 V with an accuracy of 1.5%. The device provides an active low, push-pull output and includes a reset delay time of 40 ms. It consumes a typical operating supply current of 7 uA. The component is housed in a compact SC-70-3 package and is rated for operation between -40°C and +125°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact SC-70-3 surface-mount packaging for space-constrained designs
• Fixed threshold voltage monitoring without external resistor networks

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Microprocessor system supervision
• Battery-powered instrumentation

Supervisors Procurement Notes

Verify the specific suffix 'XR30' against official datasheets to confirm the exact threshold voltage and package type. Ensure compatibility with your system's voltage levels and thermal requirements. Check for RoHS compliance status as indicated in the manufacturer documentation. Confirm availability through authorized distributors due to potential supply constraints.

Supervisors Selection Notes

Select this component when a fixed 3.0 V threshold is required for single-input voltage monitoring. Consider the 7 uA quiescent current for low-power applications. The push-pull output simplifies interface design compared to open-drain alternatives. Verify that the 40 ms reset delay meets your system's startup timing requirements.

Supervisors Part Context

Part of the MAX6326U family of ultra-low-power reset circuits. Designed for applications needing reliable power supervision in minimal footprint packages. Offers fixed thresholds to reduce design complexity and component count.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6326 series with different threshold voltages if the 3.0 V setting is not suitable. Verify electrical specifications match before substitution.
