Supervisors Procurement Notes

Verify the exact package designation against official datasheets, as distributor listings may vary between SSOT-24-4 and USP-6C descriptions. Confirm the specific threshold voltage variant matches the design requirement, as suffixes indicate different detection levels. Ensure compatibility with the target operating temperature range of -40°C to +85°C. Cross-reference the manufacturer part number directly with Torex Semiconductor documentation to avoid substitution errors.

Supervisors Selection Notes

Select this component when a fixed 4.3 V threshold is required for supervising power rails up to 6 V. Consider the low quiescent current for applications prioritizing energy efficiency. The CMOS output interface simplifies integration with digital logic families. Evaluate the 30 µs reset delay against the timing requirements of the controlled microcontroller or FPGA. Verify that the SSOT-24-4 footprint fits the available PCB space constraints.
