APX803L-33W5-7

Supervisors Overview

The APX803L-33W5-7 is a microprocessor supervisory circuit manufactured by Diodes Incorporated, designed to monitor system voltage levels within the 0.4V to 5.5V range. This specific variant features a fixed threshold voltage of 3.3V and provides an active low, open-drain reset output. It operates in surface-mount SOT-25-5 packages and supports a wide temperature range from -40°C to +125°C. The device ensures reliable system initialization by maintaining the reset signal for a specified delay period after power supply stabilization.

Supervisors Feature Summary

• Monitors system voltage to ensure proper microprocessor operation
• Provides active low open-drain reset signal generation
• Operates across extended industrial temperature ranges

Supervisors Applications

• Microprocessor system voltage monitoring
• Digital system power supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact suffix W5-7 against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.3V threshold is required for systems operating up to 5.5V input. The SOT-25-5 package suits space-constrained designs requiring five-pin configurations. Consider the extended temperature rating if the application involves harsh environmental conditions compared to standard commercial grade alternatives.

Supervisors Part Context
