DS1233DZ-5+T&R

Supervisors Overview

The DS1233DZ-5+T&R is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V, featuring a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device provides a reset delay time of 350 ms with an accuracy of 5%. It draws a working supply current of 50 uA and supports active low, open drain, or push-pull output types. Designed for surface mount installation in SOT-223 packages, it functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Detects power failures to facilitate data protection during voltage drops
• Generates system reset signals upon power loss or brown-out conditions
• Offers flexible output configurations including open drain and push-pull modes

Supervisors Applications

• Embedded systems requiring reliable power monitoring
• Microcontroller-based designs needing automatic reset generation
• Portable electronics utilizing battery backup switching mechanisms

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when sourcing this component. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure authenticity. Check RoHS compliance status for environmental regulations. Ensure the SOT-223 package type matches your PCB layout requirements. Validate the 5V threshold specification against your system's voltage levels before integration.

Supervisors Selection Notes

Select this component for applications requiring precise voltage supervision without manual reset inputs. Consider the 50 uA operating current for low-power designs. Evaluate the 350 ms reset delay against system startup timing requirements. Compare the 5% accuracy against stricter tolerance needs. Verify compatibility with open drain or push-pull interface standards used in the target design.

Supervisors Part Context

This part belongs to the DS1233 series of simple reset circuits designed for cost-sensitive applications. It complements other variants like the DS1233Z-5+ and DS1233-5+T&R, differing primarily in package style and reel configuration. The series focuses on providing essential power management functions in compact form factors suitable for space-constrained electronic devices.

Supervisors Replacement Considerations

Consider the DS1233DZ-5+ for identical specifications in tube packaging. The DS1233-5+T&R serves as a functional equivalent with through-hole mounting options. Verify pinout compatibility and electrical parameters before substituting with these related parts.
