MAX6320PUK46CY-T

Supervisors Overview

The MAX6320PUK46CY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies in digital systems with a fixed reset threshold voltage of 4.63 V and an overvoltage threshold of 4.699 V. The device features an active-low, open-drain reset output and includes integrated watchdog timer and manual reset capabilities. It operates within a supply voltage range up to 5.5 V and consumes a typical operating current of 10 uA. The component is housed in a compact SOT-23-5 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset functionality for enhanced system robustness
• Provides factory-trimmed reset threshold voltage accuracy without external components
• Features low-power operation suitable for battery-supplied applications

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for digital logic protection
• Manual reset input integration for user-initiated system recovery

Supervisors Procurement Notes

Verify the specific suffix CY against official manufacturer documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as indicated in the datasheet. Check current production status and availability through authorized distributors, as lead times may vary. Ensure the selected variant matches the required reset threshold and output configuration for the target application design.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-supply monitoring. The open-drain output allows flexibility in interfacing with various logic families. Consider the SOT-23-5 package size for space-constrained designs. Verify that the 10 uA quiescent current meets the system's power budget requirements during active monitoring phases.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. The family offers multiple combinations of reset outputs, timeout periods, and threshold voltages. The MAX6320 variant specifically provides an open-drain output stage. These devices are designed to monitor power supplies and ensure reliable system startup and operation in harsh environments.

Supervisors Replacement Considerations

Compatible substitutes within the same family include MAX6320 variants with different threshold voltages or output configurations, such as MAX6320PUKxxCX+T (push-pull) or MAX6320PUKxxBX+T (bidirectional). Cross-reference exact threshold values and package types before substitution.
