TPS3307-18MDREP

Supervisors Overview

The TPS3307-18MDREP is a triple processor voltage supervisor manufactured by Texas Instruments, designed for circuit initialization in DSP and processor-based systems. It monitors three independent supply voltages: 1.68 V, 2.93 V, and an adjustable threshold via the SENSE input. The device features a push-pull active-low RESET output with a fixed 200 ms delay to ensure proper power-up sequencing. It operates within a supply voltage range of 2 V to 6 V and supports manual reset functionality. The component is housed in an 8-pin MSOP package and is rated for an extended operating temperature range from -55°C to 125°C.

Supervisors Feature Summary

• Triple voltage monitoring capability for independent power rails
• Integrated power-on reset generator with fixed 200 ms delay
• Manual reset input for system control
• Temperature-compensated voltage reference

Supervisors Applications

• DSP and microprocessor system initialization
• Military applications requiring extended temperature performance
• Industrial equipment power supervision
• Programmable logic controller power management

Supervisors Procurement Notes

Verify the specific suffix MDREP indicates military-grade or enhanced product status when sourcing. Confirm the manufacturer's datasheet for the TPS3307-EP series to validate the exact threshold specifications and pinout compatibility. Ensure the procurement channel provides traceability documentation required for high-reliability applications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with a unified reset signal. The adjustable SENSE input allows flexibility for non-standard voltage thresholds above 1.25 V. Consider the 200 ms fixed delay for timing requirements during power-up sequences. Verify that the 8-pin MSOP package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the TPS3307 family of triple processor supervisors. It shares functional similarities with other variants like TPS3307-18DGN but differs in packaging and potentially qualification levels. The 'EP' designation typically denotes an enhanced product line with controlled baselines and diminished manufacturing source support.

Supervisors Replacement Considerations

TPS3307-18DGN serves as a commercial alternative with similar electrical characteristics but in an 8-MSOP package. For automotive applications, consider the TPS3307-Q1 series if AEC-Q100 qualification is required.
