AP1701DWG-7

Supervisors Overview

The AP1701DWG-7 is a microprocessor supervisory circuit manufactured by Diodes Incorporated, designed to monitor power supply voltages in digital systems. It operates within a supply voltage range of 2.7V to 5.5V and features a single monitored input with a typical threshold of 3.08V. The device provides an active-low push-pull reset output, ensuring system reliability by asserting the reset signal when the supply voltage drops below the preset threshold. It includes a minimum reset timeout of 100ms and functions across a temperature range of 0°C to 70°C.

Supervisors Feature Summary

• Provides precise monitoring of power-supply voltages for microprocessor and digital systems
• Features an active-low push-pull reset output configuration
• Operates without external components or adjustments
• Designed to ignore fast transients on the VCC supply line

Supervisors Applications

• Microprocessor supervisory circuits
• Digital system power management
• Portable equipment requiring low supply current

Supervisors Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels due to potential counterfeit risks. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with current design specifications. Validate thermal performance under maximum operating conditions.

Supervisors Selection Notes

Select this component for applications requiring simple voltage supervision without manual reset capabilities. Ensure the required threshold voltage aligns with the specific supply rail being monitored. Consider the SC-59-3 package size for space-constrained designs. Verify that the operating temperature range meets the environmental requirements of the target application.

Supervisors Part Context

This part belongs to the AP1701/2/3/4 series of 3-pin microprocessor reset circuits. These devices are engineered to eliminate external components and adjustments, offering a cost-effective solution for maintaining circuit reliability. The series supports various supply voltages including +5V, +3.3V, and +3.0V, making it versatile for common digital logic families.

Supervisors Replacement Considerations

Public documentation indicates that new designs should utilize the APX809 or APX810 series as replacements for the AP1701 family. Verify pinout compatibility and electrical parameter equivalence before substituting.
