DS1832U/T&R

Supervisors Overview

The DS1832U/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.64 V to 5.5 V and features a fixed threshold voltage of 3.3 V for power monitoring. The device provides active high, active low, and push-pull output configurations with a reset delay time of 610 ms. It includes an integrated watchdog timer and detects power failures without requiring manual reset or battery backup switching. Accuracy is specified at 2.5%, and quiescent current is 35 uA. Operating temperatures span from -40°C to +85°C in an UMAX-8 surface-mount package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Power failure detection capability
• Multiple output configuration options including active high, active low, and push-pull

Supervisors Applications

• Portable equipment power management
• Consumer electronics supervision
• Industrial control system monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure packaging specifications match tape-and-reel handling needs. Validate that the UMAX-8 package variant aligns with PCB footprint designs. Check for any obsolescence notices or lifecycle status updates from Analog Devices.

Supervisors Selection Notes

Select this component when a fixed 3.3 V threshold is required for voltage supervision. Consider the 610 ms reset delay and 35 uA current consumption for low-power applications. Verify compatibility with available output drive types. Ensure the operating temperature range meets environmental constraints. Evaluate the need for watchdog functionality versus simpler reset circuits.

Supervisors Part Context

The DS1832U belongs to the Maxim Integrated MicroMonitor family of supervisory circuits. These devices are designed to monitor voltage levels and provide reset signals to microprocessors and memory devices. The U suffix typically denotes a specific package or temperature grade variation within the broader product line. This series emphasizes low power consumption and compact packaging for space-constrained designs.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for qualified replacement part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution.
