Supervisors Procurement Notes

Verify the specific suffix H indicates the correct threshold and package variant against the official datasheet. Confirm AEC-Q100 automotive grade requirements align with your design specifications. Check lead times as this item may be subject to special order status. Ensure compatibility with your system's input voltage range and output load requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required for voltage supervision. The open-drain output necessitates an external pull-up resistor, which must be accounted for in the circuit design. Consider the 40 µs reset delay for timing-sensitive applications. Verify that the SOT-23-5 package fits the available PCB space and thermal constraints.
