DS1233Z-15+

Supervisors Overview

The DS1233Z-15+ is a voltage supervisory circuit from the EconoReset series manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input with a threshold voltage of 4.125 V and an overvoltage threshold of 4.24 V. The device operates within a supply voltage range up to 5.5 V and features a reset delay time of 350 ms. It offers active low, open drain, or push-pull output types with 15% accuracy. Operating current is 50 uA, and it supports power failure detection without manual reset or watchdog functions. The component is housed in an SOT-223-4 package and functions between -40°C and +85°C.

Supervisors Feature Summary

• Provides power-failure detection capability for system monitoring
• Offers flexible output configurations including active low, open drain, and push-pull modes
• Operates with low quiescent current consumption

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microprocessor reset circuits
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix Z indicates the tube packaging format when ordering. Confirm the 15% accuracy rating aligns with design requirements for the 4.125 V threshold. Ensure the SOT-223-4 footprint matches the PCB layout. Check RoHS compliance status for environmental regulations. Validate that the absence of a manual reset pin fits the system architecture.

Supervisors Selection Notes

Select this component when a fixed 4.125 V threshold is required for 5V systems. The SOT-223-4 package suits surface-mount applications needing compact sizing. Consider the 350 ms reset delay for timing constraints. The lack of manual reset simplifies design if external control is unnecessary. Verify compatibility with the target operating temperature range of -40°C to +85°C.

Supervisors Part Context

This part belongs to the DS1233 series of EconoReset supervisors. It shares functional similarities with other variants like DS1233Z-5+ but differs in threshold voltage and accuracy specifications. The series provides basic power-fail monitoring without complex features like watchdog timers or battery backup switches.

Supervisors Replacement Considerations

DS1233Z-5+ offers similar functionality with a different threshold voltage (4.625 V) and higher accuracy (5%). DS1233MS-55+ provides precision monitoring in an SOIC-8 package. Verify electrical parameters match before substitution.
