DS1813-5

Supervisors Overview

The DS1813-5 is a supervisory circuit designed for power supply monitoring applications. It utilizes a precision temperature reference and comparator to track the status of the power supply voltage (Vcc). The device generates an internal power-fail signal when out-of-tolerance conditions are detected, forcing the reset output to an active state. Upon return to tolerance, the reset signal remains active for approximately 150ms to allow system stabilization. It supports a pushbutton reset option and operates within a specified temperature range.

Supervisors Feature Summary

• Monitors power supply status using a precision temperature reference and comparator circuit
• Generates internal power-fail signal upon detection of out-of-tolerance conditions
• Maintains reset output in active state for approximately 150ms during power-up stabilization
• Supports manual reset generation via external pushbutton connected to the reset output

Supervisors Applications

• Power supply supervision in embedded systems
• Processor reset management in microcontroller circuits
• System recovery following power anomalies

Supervisors Procurement Notes

Verify RoHS compliance status as datasheet indicates leaded options may be available. Confirm package type matches TO-92 specifications. Check current availability as distribution channels may vary. Ensure operating temperature range meets application requirements. Validate pin configuration against schematic design before procurement.

Supervisors Selection Notes

Select this component for applications requiring simple power supply monitoring with minimal external components. The fixed threshold voltage suits standard 5V logic systems. Consider the pushbutton feature if manual reset capability is required. Evaluate thermal performance within the specified operating temperature range. Verify compatibility with target processor reset timing requirements.
