MAX6322HPUK46C-T

Supervisors Overview

The MAX6322HPUK46C-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies and processor activity in digital systems, housed in a 5-pin SOT-23 surface-mount package. The device features a fixed reset threshold voltage of 4.6V and supports a maximum supply voltage of 5.5V. It includes manual reset functionality and a watchdog timer to ensure system reliability. The circuit operates within an extended temperature range from -40°C to +125°C, with a typical quiescent current of 10µA and a reset delay time of 200ms.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset input for comprehensive system supervision
• Provides factory-trimmed reset threshold voltage for precise monitoring without external components
• Features low-power operation suitable for battery-supplied applications
• Offers push-pull output configuration for direct interface with logic circuits

Supervisors Applications

• Microprocessor (μP) supervisory circuits in digital systems
• Power supply monitoring for embedded controllers
• Watchdog timer implementation for fault recovery
• Manual reset input integration for user-initiated system restarts

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free specifications prior to procurement. Check production lifecycle status as availability may be limited. Ensure packaging format matches design requirements. Validate electrical parameters against official datasheets for critical applications.

Supervisors Selection Notes

Select this part when a fixed 4.6V threshold is required for system supervision. Consider the integrated watchdog and manual reset features if system robustness is a priority. Evaluate the 10µA quiescent current against power budget constraints. Verify that the SOT-23-5 package fits the PCB layout. Compare against other MAX63xx variants if different thresholds or output types are needed.

Supervisors Part Context

The MAX6322 belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. This family provides various combinations of reset outputs, watchdog timers, and manual reset inputs. The MAX6322 specifically combines a watchdog timer with a manual reset input, offering flexibility for complex system control scenarios requiring both automated and manual intervention capabilities.

Supervisors Replacement Considerations

Cross-reference with MAX6322HPUK46C+T for identical specifications. Other MAX63xx series devices may serve as alternatives if threshold voltages or output configurations differ. Verify pin compatibility and functional equivalence before substitution.
