DS1233DZ-15+

Supervisors Overview

The DS1233DZ-15+ is a single-channel voltage supervisor 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 an open-drain or open-collector active-low reset output. The device monitors one input with a threshold voltage of 4.125 V and provides a minimum reset delay time of 250 ms. It is housed in a surface-mount SOT-223-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Generates an active low reset signal when the monitored power supply exceeds tolerance limits
• Includes internal circuitry for power-fail detection and system stabilization delays
• Utilizes an open-drain output stage compatible with various logic families

Supervisors Applications

• Microprocessor system supervision
• Power management monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix against official datasheets, as packaging options such as tape-and-reel or cut tape may vary by distributor. Confirm the manufacturer part number matches the exact threshold and package requirements for your design. Cross-reference with Analog Devices documentation to ensure component authenticity and current production status before finalizing procurement orders.

Supervisors Selection Notes

Select this component for applications requiring a simple, low-power voltage monitor with a fixed threshold near 4.125 V. Ensure the system operating voltage remains within the specified 1.2 V to 5.5 V range. Consider the SOT-223-3 package constraints for PCB layout and thermal management during the selection process.

Supervisors Part Context

This part belongs to the DS1233 family of voltage supervisors designed for low-cost, low-power applications. The 'D' suffix typically indicates the SOT-223 package variant, while '15' denotes the specific voltage threshold tolerance. These devices are engineered to provide reliable reset signals for digital systems without requiring external components.

Supervisors FAQ

What is the reset delay time for the DS1233DZ-15+?

The device provides a minimum reset delay time of 250 ms to allow the power supply and system to stabilize after voltage recovery.

Does the DS1233DZ-15+ include a manual reset pin?

No, this specific model does not feature a manual reset input; it relies on automatic power-fail detection.
