DS1233Z-5

Supervisors Overview

The DS1233Z-5 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 and features a threshold voltage of 4.625 V with an accuracy of 5%. The device provides power-fail detection and utilizes an active low, open drain, push-pull output. It includes a reset delay time of 350 ms and consumes a typical operating current of 50 uA. Designed for surface-mount applications, it is housed in an SOT-223-4 package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring of power supply voltages with integrated temperature compensation.
• Generates system reset signals upon detecting out-of-tolerance power conditions.
• Includes internal pull-up resistors to simplify circuit design and reduce component count.

Supervisors Applications

• Microprocessor system power supervision
• Battery-powered equipment voltage monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix Z indicates the SOT-223-4 surface mount package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to integration. Ensure the selected variant matches the required threshold voltage and output drive characteristics for the target application circuit.

Supervisors Selection Notes

Select this component when a compact surface-mount solution is required for single-channel voltage supervision. The SOT-223-4 package offers space efficiency compared to through-hole alternatives. Consider the 5% accuracy and 350 ms reset delay to ensure compatibility with the microprocessor's startup timing requirements and noise immunity needs.

Supervisors Part Context

This part belongs to the DS1233 EconoReset family, designed to replace discrete supervisor components. It integrates a precision voltage reference and sensor to monitor a single input channel. The series is characterized by low power consumption and minimal external component requirements, facilitating reliable operation in embedded systems.

Supervisors Replacement Considerations

Compatible substitutes include DS1233Z-10+ and DS1233Z-15+, which share the same package and functionality but feature different voltage thresholds. Verify that the alternative part number meets the specific supply voltage monitoring requirements of the design.
