DS1233DZ-15+T&R

Supervisors Overview

The DS1233DZ-15+T&R is a single-channel voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It features an open-drain or open-collector output with active-low reset functionality and a minimum reset delay time of 250ms. The device monitors one input voltage with a threshold of 4.125V. Designed for surface-mount assembly, it is housed in a SOT-223-3 package. The component operates within a temperature range of -40°C to 85°C (TA) and supports supply voltages up to 5.5V.

Supervisors Feature Summary

• Provides active-low reset signal generation based on monitored power supply levels
• Features open-drain or open-collector output configuration for flexible interfacing
• Includes internal reset delay timer to ensure stable power-up sequencing

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix and packaging format against official manufacturer documentation before procurement. Confirm that the SOT-223-3 package matches the target PCB footprint requirements. Ensure the active-low reset polarity aligns with the connected logic interface specifications. Cross-reference the 4.125V threshold value with the application's voltage tolerance limits to guarantee proper supervision triggering under all operating conditions.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with open-drain output is required for systems operating between 1.2V and 5.5V. The 4.125V threshold makes it suitable for 5V logic applications requiring precise supervision. Consider the SOT-223-3 package size for space-constrained designs. Verify that the 250ms minimum reset delay meets the system's power-up timing requirements without external components.

Supervisors Part Context

This part belongs to the DS1233 family of voltage supervisors designed for cost-sensitive applications. It offers basic power monitoring capabilities without additional features like watchdog timers or manual reset inputs. The EconoReset series focuses on essential supervision functions in compact packages, serving as a fundamental building block for reliable power management in embedded systems.
