MAX6320PUK29CY-T

Supervisors Overview

The MAX6320PUK29CY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 2.9V. The device provides an active-low, open-drain reset output with a typical timeout period of 200ms. It includes integrated watchdog timer functionality and a manual reset input for system control. Packaged in a compact SOT-23-5 surface-mount format, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset capabilities for comprehensive system supervision
• Provides factory-trimmed reset threshold voltages for precise power monitoring
• Features low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power supply monitoring in portable electronic devices
• Watchdog timer implementation in digital controllers

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the exact threshold voltage code matches the required 2.9V specification. Check RoHS compliance status and lead times due to potential limited availability. Ensure the operating temperature range meets the application's environmental requirements.

Supervisors Selection Notes

Select this component when a fixed 2.9V reset threshold is required alongside watchdog functionality. Compare against other MAX63xx variants if different timeout periods or output types are needed. Consider the SOT-23-5 package size constraints during PCB layout. Verify compatibility with the target microprocessor's reset signal requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. These devices monitor power supplies and processor activity in digital systems. The family offers various combinations of reset outputs, watchdog timers, and manual resets in a miniature package.

Supervisors Replacement Considerations

Direct replacements include other MAX6320 variants with different threshold voltages (e.g., MAX6320PUK34CW+T) if voltage levels differ. Cross-reference with MAX6316 or MAX6322 series parts for similar functionality but different timeout characteristics.
