DS1233AZ-15+T&R

Supervisors Overview

The DS1233AZ-15+T&R is a single-channel voltage supervisor IC from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors supply voltages within the 1.1V to 5.5V range, featuring a fixed reset threshold of 4.625V and an overvoltage threshold of 4.75V. The device operates with a maximum supply voltage of 5.5V and draws only 50µA of quiescent current. It provides a reset delay time of 350ms and offers active low output in open drain or push-pull configurations. The component supports power-fail detection and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single-channel applications without requiring external components.
• Detects power failures to support data preservation strategies during unexpected voltage drops.
• Offers flexible output drive capabilities through selectable open drain or push-pull modes.

Supervisors Applications

• Embedded systems requiring reliable power monitoring
• Microcontroller-based designs needing automatic reset generation
• Industrial equipment operating in harsh thermal environments

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements before integration. Confirm RoHS compliance status and environmental certifications as required by your procurement standards. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is sufficient for the target voltage rail. Consider the 50µA quiescent current for battery-sensitive designs. Evaluate the 350ms reset delay against system startup timing requirements. Verify that the SOT-223-3 package fits the available PCB footprint constraints.

Supervisors Part Context

This device belongs to the DS1233A family of simple reset circuits designed for cost-sensitive applications. It eliminates the need for complex external resistor networks typically required in discrete supervisor designs. The EconoReset series focuses on providing essential monitoring functions in compact packages suitable for space-constrained electronics.
