DS1815-5+

Supervisors Overview

The DS1815-5+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, belonging to the EconoReset series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a threshold voltage of 4.62 V with an overvoltage threshold of 3.15 V. The device provides a reset delay time of 150 ms minimum and consumes a working supply current of 35 uA. It utilizes a TO-92-3 through-hole package and supports an active low push-pull output. The component functions across a temperature range of -40°C to +85°C and includes power failure detection capabilities without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Integrates power failure detection for monitoring supply integrity
• Features active low push-pull output configuration
• Provides fixed reset timeout duration for system stability

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microcontroller-based designs needing automatic reset on brown-out
• Industrial control circuits operating in varying thermal environments

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package type matches design requirements as variations exist within the family. Check datasheet for specific electrical characteristics relevant to the target application environment. Ensure compliance with RoHS directives if required by project specifications. Validate lead times as production status may impact immediate fulfillment needs.

Supervisors Selection Notes

Choose this component when a simple, low-power supervisor is needed for single-channel monitoring. The TO-92-3 package suits through-hole assembly processes. Consider the fixed threshold voltage suitability for standard logic levels. Evaluate the absence of manual reset against system safety requirements. Assess the operating temperature range against environmental constraints.
