DS1831AS+

Supervisors Overview

The DS1831AS+ is a multisupply micromonitor manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for supervisory circuit applications. It features an SOIC-Narrow-16 surface-mount package and operates within a temperature range of -40°C to +85°C. The device monitors two input channels with threshold voltages set at 3.3 V and 5 V. Key electrical parameters include a maximum supply voltage of 5.5 V, a reset delay time of 1.6 s, and a typical operating supply current of 80 uA. Accuracy is specified at 2.5%, with overvoltage thresholds at 2.64 V and 4.75 V.

Supervisors Feature Summary

• Integrates a watchdog timer function for system reliability monitoring alongside dual-channel voltage supervision.
• Provides manual reset capability via a dedicated input pin for controlled system restarts.
• Features active low, open-drain output configuration for flexible interfacing with logic circuits.

Supervisors Applications

• Multisupply power system monitoring in embedded electronics
• Voltage supervision for microprocessor-based systems requiring manual reset
• Industrial control units operating within extended temperature ranges

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific manufacturing lot codes prior to procurement. Ensure that the SOIC-Narrow-16 package variant matches design requirements, as packaging formats may vary across production batches. Cross-reference datasheet specifications against current inventory records to confirm operational readiness.

Supervisors Selection Notes

Select this component when dual-voltage supervision with integrated watchdog functionality is required in a compact surface-mount form factor. The fixed 3.3 V and 5 V thresholds suit standard logic levels without external resistor networks. Consider the 80 uA quiescent current for low-power designs. Verify that the manual reset feature aligns with system recovery protocols before finalizing the selection.

Supervisors Part Context

The DS1831AS+ belongs to the DS1831A series of multisupply micromonitors from Analog Devices/Maxim Integrated. This series focuses on providing comprehensive power management supervision in small packages. The 'AS' suffix typically denotes the specific package type and temperature grade, distinguishing it from other variants like the DIP or S versions within the same functional family.
