DS1832+

Supervisors Overview

The DS1832+ is a MicroMonitor supervisory circuit designed for single-supply voltage monitoring. It features a fixed threshold of 3.3 V with an accuracy of 2.5%. The device operates within a supply voltage range up to 5.5 V and consumes 35 uA of quiescent current. It includes a built-in watchdog timer and provides reset output after a delay of 610 ms. The component supports active high, active low, and push-pull outputs without manual reset or battery backup switching capabilities.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides configurable reset output polarity options
• Features low power consumption suitable for battery-operated systems

Supervisors Applications

• Single-supply voltage supervision in embedded systems
• Watchdog timer implementation for microcontroller protection
• Power failure detection circuits

Supervisors Procurement Notes

Verify availability status as the component may be subject to limited supply or discontinuation. Confirm RoHS compliance details and check for alternative sourcing channels if standard distribution is unavailable. Ensure the specific suffix matches required package and temperature specifications.

Supervisors Selection Notes

Select this part when a single-channel voltage monitor with integrated watchdog functionality is required. Consider the 3.3 V threshold and 610 ms reset delay against system timing requirements. Evaluate the UMAX-8 package constraints and operating temperature range for environmental compatibility.

Supervisors Part Context

The DS1832+ belongs to the Maxim Integrated MicroMonitor family of supervisory circuits. These devices are designed to monitor power supply voltages and provide reset signals to protect electronic systems from malfunction due to under-voltage conditions or software faults via the watchdog feature.
