2T13K33MDBVREP

Overview

The Texas Instruments 2T13K33MDBVREP is a military-enhanced voltage supervisory circuit designed for processor support applications. It operates within a supply voltage range up to 6 V and features a fixed threshold voltage of 2.93 V. The device provides an active low, open drain output with a reset delay time of 30 ms. It includes an integrated watchdog timer but lacks manual reset and battery backup switch functionalities. The component is housed in an SOT-23-6 surface-mount package and supports operation across a temperature range from -55 °C to +125 °C.

Feature Summary

• Military-grade enhanced reliability for harsh environments
• Integrated watchdog timer for system stability
• Single-channel voltage supervision with open-drain output

Applications

• Processor support circuits in defense systems
• Avionics monitoring applications
• Industrial control systems requiring high reliability

Procurement Notes

Verify the specific suffix MDBVREP confirms the SOT-23-6 package and mil-enhanced status. Confirm RoHS compliance details as specified in the official datasheet. Ensure the ordering part number matches the exact electrical characteristics required for your design, particularly the 2.93 V threshold and 30 ms delay timing.

Selection Notes

Select this component when a single-supply supervisor with watchdog functionality is required for critical systems. The fixed 2.93 V threshold suits 3.3 V logic families. Consider the SOT-23-6 footprint for space-constrained PCB layouts. Verify that the active-low open-drain output aligns with the target microcontroller's reset input requirements.

Part Context

This part belongs to the TPS3813K33 series of voltage supervisors. The '2T' prefix typically denotes a specific military or enhanced variant configuration within Texas Instruments' portfolio. It shares core architecture with commercial counterparts but undergoes stricter screening and qualification processes for aerospace and defense use cases.

Replacement Considerations

Direct substitutes include TPS3813K33MDBVREP. Verify pinout compatibility and electrical parameter alignment before substitution.
