MAX6326UR23

Supervisors Overview

The MAX6326UR23+T is a supervisory circuit from the MAX6326 family, designed as an ultra-low-power reset circuit in a 3-pin SC70/SOT-23 package. It monitors a single voltage input with a fixed threshold of 2.3V. The device features an active-low push-pull output and includes a manual reset (MR) input for system control. It operates within a supply voltage range of 1.0V to 5.5V, drawing only 3.3µA of quiescent current. The reset delay time is typically 2ms, and it functions across an industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Integrated manual reset input for external control
• Active-low push-pull output driver
• Fixed internal threshold voltage eliminates external components

Supervisors Applications

• Microprocessor supervision in portable electronics
• Battery-powered instrumentation monitoring
• Consumer devices requiring low standby current
• Industrial control systems needing reliable reset signals

Supervisors Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation matches Analog Devices or Maxim Integrated, as both entities produce this component line. Ensure the part number corresponds to the 2.3V threshold variant. Check RoHS compliance status if required by your manufacturing standards. Validate availability through authorized distributors due to potential limited stock situations.

Supervisors Selection Notes

Select this component when a fixed 2.3V threshold is required for voltage monitoring. The manual reset feature distinguishes it from variants without MR inputs. Consider the 3.3µA quiescent current for power-sensitive designs. The SOT-23-3 package offers space efficiency for compact PCB layouts. Verify that the active-low output polarity matches your system logic requirements.

Supervisors Part Context

This part belongs to the MAX6326 series of microprocessor supervisors. It shares the family's core architecture but differs in threshold voltage and pin configuration from other members like the MAX6328 or MAX6333. The 'UR' prefix denotes the SOT-23 package, while '23' specifies the 2.3V trip point. It is distinct from the ADPL62083 series which offers adjustable thresholds.

Supervisors Replacement Considerations

Direct substitutes include other MAX6326 variants with different thresholds if voltage levels change. The MAX6328 series offers similar functionality but may lack the manual reset input. Cross-reference with MAX6333 series for comparable performance in different packages. Ensure any replacement maintains the same output type and quiescent current specifications.
