MAX6326XR23-T

Supervisors Overview

The MAX6326XR23-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supply voltages in digital systems and asserts an active-low, push-pull reset signal when the VCC voltage drops below a preset threshold of 2.32V. The device features a typical reset delay time of 185ms and operates within a supply voltage range up to 5.5V. It consumes ultra-low supply current of 500nA and maintains accuracy of 1.5%. The component is housed in a compact SOT-23-3 package and supports surface mount installation across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring of power-supply voltages with factory-trimmed thresholds
• Features ultra-low supply current consumption suitable for portable applications
• Delivers an active-low, push-pull reset output signal

Supervisors Applications

• Portable and battery-powered equipment
• Microprocessor and microcontroller systems
• Computers and intelligent instruments

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as standard listings often use 'MAX6326UR23+T' or similar variants. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the specific revision matches design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component for designs requiring low-power supervision in space-constrained environments. The SOT-23-3 package minimizes board area usage. Verify that the 2.32V threshold aligns with the target system's voltage rails. Consider the 500nA quiescent current impact on overall battery life for extended deployment scenarios.

Supervisors Part Context

This part belongs to the MAX6326U family of ultra-low-power SC70/SOT microprocessor reset circuits. These devices eliminate external components and adjustments for 2.5V, 3V, 3.3V, and 5V powered circuits. The family ensures reliable operation by ignoring fast transients on the VCC line while maintaining correct states down to 1V.

Supervisors Replacement Considerations

Compatible substitutes include other MAX6326 variants with different threshold voltages or output types (e.g., open-drain). Cross-reference pinouts and electrical characteristics carefully to ensure functional equivalence without redesigning the surrounding circuitry.
