STM6322LWY6F

Supervisors Overview

The STM6322LWY6F is a single-channel power supply management circuit manufactured by STMicroelectronics. It functions as a voltage supervisor with an integrated watchdog timer and push-button reset capability, housed in a PDSO5 package (SOT-23). The device monitors one input channel and features a reset threshold voltage of 4.63V. It operates within a temperature range of -40°C to +85°C and supports a maximum supply voltage of 5.5V.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes manual push-button reset functionality
• Provides precise voltage supervision with fixed threshold

Supervisors Applications

• Embedded systems requiring hardware-level fault detection
• Microcontroller reset circuits in industrial environments
• Portable devices needing low-power supervision

Supervisors Procurement Notes

Verify the specific suffix '6F' against official STMicroelectronics documentation to confirm tape-and-reel packaging specifications and exact threshold tolerances. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Cross-reference the part number with current datasheets to validate operating temperature ranges and electrical characteristics before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a combined solution for voltage supervision, watchdog timing, and manual reset is required in a minimal footprint. It is suitable for designs where space constraints preclude discrete components. Consider the fixed 4.63V threshold against the system's nominal supply voltage to ensure proper reset triggering under all operating conditions.

Supervisors Part Context

This part belongs to the STM632x series of supervisors from STMicroelectronics, designed for cost-effective power management. These devices are commonly used in consumer electronics and industrial control applications where reliable system resets are critical. The series offers various threshold voltages and package options to suit different design requirements.

Supervisors Replacement Considerations

Check for STM6321 or STM682x series variants if different reset thresholds or feature sets are needed. Verify pinout compatibility and electrical specifications before substituting.
