MAX6322HPUK46C

Supervisors Overview

The MAX6322HPUK46C+T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 4.6V and operates within a supply voltage range up to 5.5V. The device provides a push-pull output type with active high and active low capabilities. It includes manual reset functionality but lacks a watchdog timer or battery backup switch. The component supports a reset delay time of 1.4 ms and consumes a typical operating current of 3 uA. It is housed in a SOT-23-5 package and functions reliably across an industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Monitors power supply voltages and microprocessor activity for system stability
• Includes manual reset input for user-initiated system control
• Offers configurable push-pull reset outputs with active high/low options

Supervisors Applications

• Digital systems requiring power supply supervision
• Microprocessor activity monitoring circuits
• Embedded systems needing manual reset capability

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details through official manufacturer documentation before procurement. Ensure the specific suffix matches required electrical characteristics. Cross-reference datasheet revisions to confirm pinout and functional consistency. Validate thermal performance requirements against the specified operating temperature range.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for voltage supervision. Choose this part if manual reset functionality is necessary without watchdog timer complexity. Consider the SOT-23-5 package for space-constrained surface-mount designs. Verify that the 3 uA quiescent current meets low-power design constraints. Ensure the 5.5V maximum supply voltage aligns with the target system's power rails.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits manufactured by Analog Devices Inc./Maxim Integrated. The family offers various combinations of reset outputs and timeout periods. These devices are factory-trimmed for precise threshold voltages ranging from 2.5V to 5V. The series is designed for reliable operation in digital systems requiring robust power management and reset generation.

Supervisors Replacement Considerations

Check for other variants within the MAX6316–MAX6322 family that share the same SOT-23-5 package and 4.6V threshold. Verify compatibility of reset output types and manual reset inputs with existing circuit designs. Ensure replacement parts maintain the same operating temperature range and supply voltage specifications.
