STM6717TWWY6F

Supervisors Overview

The STM6717TWWY6F is a dual-channel ultra-low power voltage supervisor manufactured by STMicroelectronics. It monitors two independent supply rails, VCC1 and VCC2, with factory-programmed reset thresholds of 3.075V and 1.665V respectively. The device features an open-drain reset output and operates within a supply voltage range up to 5.5V. It provides a typical reset delay time of 140ms on power-up. The component is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Procurement Notes

Verify the specific suffix 'TWWY6F' against the official STMicroelectronics datasheet to confirm the exact threshold voltages and package variant. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement to meet assembly standards.

Supervisors Selection Notes

Select this component when dual-supply monitoring is required in space-constrained designs. The fixed thresholds eliminate external resistor programming, simplifying the bill of materials. Consider the open-drain output capability for interfacing with various logic levels. Evaluate the low quiescent current benefit for applications prioritizing extended battery life over high-speed response times.

Supervisors Part Context

This part belongs to the STM6717 series of multi-voltage supervisors from STMicroelectronics. It shares the same core architecture as other variants in the family but differs in specific threshold settings and package options. The series is designed to provide reliable microprocessor reset signals for complex digital systems requiring multiple power domain oversight.

Supervisors Replacement Considerations

Compatible substitutes include STM6717SVWY6F and STM6718TWWY6F. Verify that the replacement part matches the required reset threshold voltages and output configuration. Ensure the alternative component maintains compatibility with the target PCB footprint and operating temperature range.
