DS1832U+

Supervisors Overview

The DS1832U+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage input with a threshold of 3.3 V and supports a maximum supply voltage of 5.5 V. The device features an active high, active low, push-pull output type and includes a watchdog timer. It has a reset delay time of 610 ms and operates within a temperature range of -40°C to +85°C. The accuracy is specified at 2.5%, with a typical operating supply current of 35 uA. Overvoltage thresholds are available at 2.64 V and 2.97 V. It is housed in an 8-pin UMAX package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Push-pull output configuration for flexible interfacing
• Power failure detection capability
• Single-channel voltage monitoring

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Industrial control unit monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as availability may be limited. Ensure the specific suffix matches design requirements without assuming functional changes from packaging variations.

Supervisors Selection Notes

Select this component when a single-supply voltage monitor with integrated watchdog functionality is required. Verify that the 3.3 V threshold aligns with the target rail. Consider the 610 ms reset delay for timing constraints. Evaluate the 35 uA quiescent current against power budget requirements.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for supervising voltage levels in digital systems. It combines voltage monitoring with watchdog timer functions in a compact surface-mount package. The series targets applications requiring reliable system resets and fault detection.

Supervisors Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same product family. Verify electrical parameter equivalence before substitution.
