DS1831AS+T&R

Supervisors Overview

The DS1831AS+T&R is a multisupply micromonitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a supervisory circuit designed to monitor multiple power rails simultaneously. The device features an active low, open-drain output and supports manual reset functionality. It operates within a supply voltage range of 1V to 5.5V and includes a reset delay time of 75 ms. The component is available in an SOIC-8 surface-mount package and is supplied in a tape-and-reel format for automated assembly processes.

Supervisors Feature Summary

• Simultaneous monitoring of multiple power supply voltages
• Manual reset input capability for system control
• Active low open-drain reset output interface

Supervisors Applications

• Multisupply voltage monitoring in embedded systems
• Power management supervision in industrial equipment
• System reset sequencing in portable electronics

Supervisors Procurement Notes

Verify the specific suffix 'AS' against the manufacturer's current product line documentation to confirm availability and exact electrical specifications. Ensure the tape-and-reel packaging configuration matches the required quantity for production lines. Cross-reference the RoHS compliance status with the latest datasheet revision to meet environmental regulations. Confirm that the SOIC-8 footprint aligns with the target PCB design constraints.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required without external comparator circuits. The integrated manual reset feature provides direct user control over system recovery states. Consider the 75 ms reset delay duration to ensure compatibility with the startup timing requirements of downstream logic components. Verify that the operating temperature range meets the environmental conditions of the intended application environment.

Supervisors Part Context

This part belongs to the DS1831 series of micromonitors from Maxim Integrated, now part of Analog Devices. These devices are designed for applications requiring reliable power supervision across multiple inputs. The series typically offers fixed threshold voltages and compact packaging solutions suitable for space-constrained designs. The '+T&R' designation indicates the specific reel packaging variant of the standard DS1831AS device.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternative part numbers. Check for pin-compatible upgrades or functional equivalents within the same product family. Ensure any replacement maintains the required number of monitored inputs and output polarity characteristics.
