DS1233D-10/T&R

Supervisors Overview

The DS1233D-10/T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed undervoltage threshold of 4.375 V. The device provides an active-low reset signal with a minimum timeout of 250 ms. It utilizes open-drain or open-collector output topology and is housed in a TO-92-3 (TO-226AA) through-hole package. The component supports manual reset functionality and includes power-fail detection capabilities.

Supervisors Feature Summary

• Provides precise monitoring of a single voltage rail using a temperature-compensated reference circuit
• Generates system reset signals upon detecting under-voltage conditions below the specified threshold
• Includes manual reset input capability for external control of the reset state

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Battery-powered equipment requiring low quiescent current
• Portable instrumentation and handheld devices

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as it determines the packaging format. The 'T&R' suffix indicates tape and reel packaging, which differs from bulk or individual tube configurations. Confirm that the manufacturer part number matches the required threshold voltage and package type exactly. Ensure compatibility with the intended board assembly process for the TO-92-3 through-hole mounting style.

Supervisors Selection Notes

Select this component when a fixed 4.375 V threshold is required for 5 V logic systems. The open-drain output allows for flexible interfacing with various logic families. Consider the 250 ms minimum reset timeout for applications requiring extended stabilization periods. Verify that the through-hole TO-92-3 package aligns with the mechanical design constraints of the target enclosure.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset family, designed for cost-sensitive applications requiring reliable power management. The DS1233 series offers a balance of precision and simplicity for basic supervisory tasks. Analog Devices acquired Maxim Integrated, consolidating these legacy product lines into their broader portfolio of power management solutions.
