DS1233D-5

Supervisors Overview

The DS1233D-5 is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors a single input with a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device features an active low, open drain, push-pull output type and includes power fail detection. It operates within a supply voltage range up to 5.5 V and has a reset delay time of 350 ms. The component functions without manual reset or watchdog timer capabilities. It is housed in a TO-92-3 package and supports surface mount installation. The operating temperature range spans from -40°C to +85°C, with an accuracy of 5% and a typical operating supply current of 50 uA.

Supervisors Feature Summary

• Provides automatic system reset upon detecting power supply anomalies
• Integrates power-fail monitoring for comprehensive voltage supervision
• Delivers active low output signals compatible with digital logic interfaces

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix D-5 against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status as manufacturing updates may alter environmental declarations. Ensure the TO-92-3 package matches your PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor for a single rail is required. The 4.625 V threshold suits 5 V systems. Consider the TO-92-3 package for through-hole designs. Verify that the 350 ms reset delay meets system timing constraints. Check if the lack of manual reset functionality aligns with design needs. Compare operating current consumption against battery life requirements for portable applications.

Supervisors Part Context

This part belongs to the DS1233 family of EconoReset supervisors. These devices are designed for cost-sensitive applications requiring basic voltage monitoring. The family typically offers various threshold voltages and package options. Analog Devices acquired Maxim Integrated, which originally developed this line. The DS1233 series focuses on simplicity and reliability for standard microprocessor reset generation.

Supervisors Replacement Considerations

Check for DS1233 variants with different thresholds or packages. Verify compatibility with DS1233-5+T&R for reel packaging needs. Ensure any substitute maintains the 4.625 V threshold and TO-92-3 form factor.
