DS1817-10

Supervisors Overview

The DS1817-10 is a single-channel voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors one supply voltage and provides a push-pull, totem-pole reset output with a high logic level. The device features a minimum reset timeout of 100ms. It operates within an ambient temperature range of -40°C to +85°C. The component is housed in a TO-92-3 through-hole package.

Supervisors Feature Summary

• Monitors a single power supply voltage for system integrity
• Provides a high-level active reset output signal
• Ensures reliable system startup with a minimum 100ms timeout period

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered systems requiring supervision
• Embedded controller power monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm the exact threshold voltage and timeout characteristics. Ensure the TO-92-3 through-hole package matches the target PCB footprint requirements. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.

Supervisors Selection Notes

Select this component when a simple, low-pin-count solution is required for single-voltage supervision. The fixed timeout and threshold simplify design compared to programmable alternatives. Consider the through-hole mounting constraint and the specific operating temperature range suitable for the intended environment.

Supervisors Part Context

This part belongs to the Maxim Integrated line of supervisory circuits, now under Analog Devices. These devices are designed to ensure microprocessors and digital logic operate correctly by detecting power failures or brown-out conditions. The series offers various packages and thresholds to suit different board layouts and voltage rails.

Supervisors Replacement Considerations

Direct substitutes include other parts from the DS1817 family with compatible pinouts and similar electrical specifications. Verify that any replacement maintains the same TO-92-3 package and meets the required voltage threshold and timeout duration for the application.
