DS1233DZ-10/T&R

Supervisors Overview

The DS1233DZ-10/T&R is a single-channel voltage supervisor IC from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors one input voltage with a threshold of 4.375V and an overvoltage threshold of 2.97V. The device features an active low open drain or push-pull output with a reset delay time of 350 ms. It operates within a supply voltage range of 1.2 V to 5.5 V and consumes 50 uA of operating current. The component is housed in a SOT-223-3 package and supports power failure detection.

Supervisors Feature Summary

• Provides simple reset and power-fail detection for single-channel monitoring
• Features active low output with open drain or push-pull configuration
• Includes power-fail detection capability without manual reset or watchdog timer

Supervisors Applications

• Processor supervision in embedded systems
• Power management circuits requiring voltage monitoring
• Industrial control systems needing reliable reset signals

Supervisors Procurement Notes

Verify the exact suffix 'T&R' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the SOT-223-3 package matches your PCB footprint requirements. Check RoHS compliance status if required by your manufacturing standards. Validate the specific threshold voltage of 4.375V against your system design needs.

Supervisors Selection Notes

Select this component for applications requiring a single-supply voltage monitor with a 4.375V threshold. The SOT-223-3 package suits surface-mount designs with space constraints. Consider the 50 uA quiescent current for low-power systems. The absence of a manual reset pin simplifies circuit design where software reset is preferred. Verify the 350 ms reset delay meets your system startup timing requirements.

Supervisors Part Context

This part belongs to the DS1233 family of EconoReset supervisors. It is designed for cost-sensitive applications requiring basic voltage monitoring. The T&R suffix denotes tape and reel packaging for automated assembly. Analog Devices acquired Maxim Integrated, hence the dual branding on documentation.

Supervisors Replacement Considerations

DS1233DZ-10+ is a compatible leaded version in TO-226AA/TO-92-3 package. DS1233D-15 offers a different threshold voltage. Verify pinout compatibility before substitution.
