DS1233A-15+

Supervisors Overview

The DS1233A-15+ is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 3.3 V and features a threshold voltage of 4.125 V with an accuracy of 15%. The device provides a reset delay time of 350 ms and detects power failures. It draws a working supply current of 50 uA and includes an overvoltage threshold of 2.8 V. The component supports active low, open drain, and push-pull output types, lacks manual reset or watchdog functions, and is housed in a TO-92-3 package for through-hole mounting.

Supervisors Feature Summary

• Monitors single input voltage levels to ensure system stability
• Detects power failure conditions for critical protection
• Provides configurable active low, open drain, or push-pull outputs

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microcontroller-based designs needing automatic reset on voltage drop
• Industrial control circuits operating within specified temperature ranges

Supervisors Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance when sourcing. Confirm the TO-92-3 through-hole package matches your PCB layout requirements. Check manufacturer documentation for RoHS status details. Ensure the 3.3 V maximum supply voltage aligns with your system design. Validate availability as distribution channels may report limited stock.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is required for low-voltage applications. The TO-92-3 package suits through-hole prototyping or specific mechanical constraints. Consider the 15% accuracy tolerance against stricter monitoring needs. Evaluate the 350 ms reset delay against processor startup times. Verify that the absence of a watchdog timer meets your safety requirements.

Supervisors Part Context

This part belongs to the DS1233A series of simple reset supervisors. It complements other variants like the DS1233A-10+ which offers different threshold accuracy. The series focuses on cost-effective power management solutions. Analog Devices acquired Maxim Integrated, unifying these product lines under one manufacturer portfolio for consistent support.

Supervisors Replacement Considerations

DS1233A-10+ offers similar functionality with different accuracy specifications.
