2U3836K33QDBVRG4Q1

Overview

The 2U3836K33QDBVRG4Q1 is a voltage supervisory circuit from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It monitors a single input voltage and provides an active-low, push-pull reset output. The device features a manual reset function and operates within a supply voltage range up to 6 V. Key electrical parameters include threshold voltages of 1.71 V and 2.79 V, a reset delay time of 200 ms, and a typical quiescent current of 220 nA. It is housed in a SOT-23-5 package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Ultra-low static current consumption for battery efficiency
• Integrated manual reset capability for system control
• Push-pull output driver for robust signal integrity

Applications

• Automotive electronic control units requiring voltage supervision
• Battery-powered systems needing low standby current
• Microcontroller power management circuits
• Industrial monitoring systems with manual reset requirements

Procurement Notes

Verify the specific suffix G4Q1 against official Texas Instruments documentation to confirm exact threshold and packaging specifications. Confirm availability status as this part number may be discontinued or subject to long lead times. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Cross-reference with equivalent TPS3836 variants if direct substitution is required.

Selection Notes

Select this component when automotive qualification and ultra-low quiescent current are critical design constraints. The active-low push-pull output suits interfaces requiring strong drive capability. Verify that the monitored voltage levels align with the available threshold options. Consider the manual reset feature if system recovery requires user intervention. Ensure the operating temperature range meets the application environment.
