DS1832U

Supervisors Overview

The DS1832U+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It features a single voltage monitor input with a threshold of 3.3 V and an accuracy of 2.5%. The device operates within a supply voltage range up to 5.5 V and includes a watchdog timer with a reset delay time of 610 ms. It supports active high, active low, and push-pull output types without manual reset or battery backup switching capabilities. The component functions reliably across a temperature range of -40°C to +85°C, consuming 35 µA of operating current.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Provides configurable output logic states including active high, active low, and push-pull configurations
• Detects power failures to ensure system integrity during voltage anomalies

Supervisors Applications

• Embedded systems requiring voltage supervision
• Industrial control units needing watchdog functionality
• Consumer electronics with power failure detection requirements

Supervisors Procurement Notes

Verify the specific suffix designation, as the provided data references DS1832U+. Confirm package availability in UMAX-8 format. Check current distribution status, as limited supply conditions may apply. Ensure compatibility with the required 3.3 V threshold and 5.5 V maximum supply voltage specifications before integration into the design.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with integrated watchdog is required. It is suitable for designs needing 3.3 V threshold detection with 2.5% accuracy. Consider the UMAX-8 surface mount package for space-constrained applications. Verify that the 610 ms reset delay meets the system timing requirements.
