STM6322TWY6F

Supervisors Overview

The STM6322TWY6F is a supervisory circuit manufactured by STMicroelectronics, designed for processor monitoring applications. It operates within a supply voltage range of 1 V to 5.5 V and features a reset threshold voltage of 3.08 V. The device provides active low or active high reset outputs with open drain or push-pull configurations. It includes a watchdog timer function and supports manual reset input via a push-button interface. The component is housed in a 5-pin SOT-23 package and is rated for an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset input functionality
• Offers configurable reset output polarity and drive type

Supervisors Applications

• Processor supervisor circuits
• Watchdog timer implementations
• Power supply management systems

Supervisors Procurement Notes

Verify the specific suffix 'TWY6F' against the official STMicroelectronics datasheet to confirm pinout, electrical characteristics, and package details. Ensure compatibility with the target application's voltage levels and temperature requirements. Cross-reference the ordering information with authorized distributors to validate part authenticity and current availability status before procurement.

Supervisors Selection Notes

Select this component when a supervisory circuit with integrated watchdog and manual reset capabilities is required. Consider the 3.08 V threshold voltage relative to the monitored supply rail. Evaluate the need for open drain versus push-pull outputs based on downstream logic interface requirements. Confirm that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

The STM6322 belongs to the STM632x/STM682x family of supervisory circuits from STMicroelectronics. This family typically includes variants with different reset thresholds and feature sets, such as the presence or absence of watchdog timers and manual reset inputs. The STM6322 specifically combines supervision with watchdog and manual reset functions in a compact 5-pin package.

Supervisors Replacement Considerations

Potential substitutes within the same family include STM6321TWY6F (without manual reset) or STM6822TWY6F (with different output configuration). Verify functional equivalence regarding reset threshold, watchdog timeout, and package dimensions before substitution.
