DS1233AZ-15

Supervisors Overview

The DS1233AZ-15 is a voltage supervisory circuit from the EconoReset family, designed to monitor power supply levels in electronic systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 3.3 V with a tolerance accuracy of 15%. The device provides an active low, open-drain reset output and includes manual reset functionality. It has a reset delay time of 450 ms and consumes a typical operating current of 50 uA. The component supports power-fail detection and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides automatic system reset when monitored voltage drops below or exceeds specified thresholds
• Includes manual reset input for user-initiated system restarts
• Features low power consumption suitable for battery-operated applications
• Generates power-fail signal to indicate out-of-tolerance conditions

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered portable devices requiring voltage supervision
• Industrial control systems needing reliable reset generation
• Embedded systems with strict power management requirements

Supervisors Procurement Notes

Verify exact suffix specifications as package and tolerance variants exist within the DS1233 series. Confirm RoHS compliance status through official documentation. Check availability status as some variants may be discontinued or have limited stock. Ensure correct pinout configuration matches your PCB layout requirements. Validate temperature range suitability for your specific application environment.

Supervisors Selection Notes

Select this variant when a 3.3 V threshold with 15% accuracy meets your design needs. Consider the SOT-223-3 package for surface mount applications. Evaluate if the 450 ms reset delay aligns with your system startup timing requirements. Compare against other series members like DS1233Z-15+ for different package options or DS1233MS-55+ for higher precision needs.

Supervisors Part Context

The DS1233AZ-15 belongs to Maxim Integrated's EconoReset line of voltage supervisors. This family offers compact solutions for power management in embedded systems. The AZ suffix typically indicates specific packaging or testing configurations within the broader DS1233 product portfolio. These devices are widely used in consumer electronics, industrial equipment, and telecommunications infrastructure.

Supervisors Replacement Considerations

DS1233Z-15+ offers similar functionality in SOIC-8 package. DS1233A-15+ provides TO-92-3 through-hole option. ASM1233D-L/1233D/1233M from ON Semiconductor serves as functional alternative with comparable specifications.
