DS1233DZ-5

Supervisors Overview

The DS1233DZ-5+ is a voltage supervisory circuit from the EconoReset series, designed for monitoring single power supply inputs. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.625 V with 5% accuracy. The device provides an active low reset signal via open drain or push-pull output types, with a reset delay time of 350 ms. It includes power-fail detection capabilities but lacks manual reset, watchdog timer, or battery backup switch functions. Operating current is 50 uA, and it supports surface mount installation in an SOT-223-4 package across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides precise voltage supervision with integrated power-fail detection for system reliability
• Offers flexible output configuration supporting both active low open drain and push-pull modes
• Ensures stable system initialization through a defined 350 ms reset delay period

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Voltage supervision for industrial control circuits
• Power management in consumer electronic devices requiring reliable reset sequences

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm exact electrical parameters and package type. Ensure compatibility with existing board layouts regarding the SOT-223-4 footprint. Confirm RoHS compliance status and operating temperature range requirements match the intended application environment before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with low quiescent current is required. Consider the available output drive options if interfacing with different logic families. Evaluate the fixed reset delay duration against system startup timing constraints. Verify that the absence of manual reset and watchdog features aligns with the overall system architecture design requirements.
