TPS3836E18DBVT

Supervisors Overview

The TPS3836E18DBVT is a NanoPower Supervisory Circuit manufactured by Texas Instruments, designed for monitoring single voltage rails in portable and battery-operated systems. It operates within a supply voltage range of 1.5 V to 6 V with a typical quiescent current of 220 nA. The device features a fixed reset threshold voltage of 1.71 V and an accuracy of 1.75%. It provides a manual reset input and offers selectable reset delay times of 10 ms or 200 ms via the RESET pin configuration. The output driver is active-low push-pull, housed in a compact SOT-23-5 package suitable for surface-mount applications across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption with typical 220 nA operating current for extended battery life
• Configurable reset delay time selectable between 10 ms and 200 ms
• Active-low push-pull output driver for direct interface with logic circuits
• Manual reset capability allowing external control over system initialization

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-powered embedded systems needing reliable power supervision
• Microcontroller and DSP power management circuits
• Industrial control systems operating in harsh environments

Supervisors Procurement Notes

Verify the specific suffix 'E18' confirms the 1.71 V threshold and 'V' indicates the SOT-23-5 package variant. Confirm RoHS compliance status as detailed in the official datasheet. Ensure the selected distributor provides genuine Texas Instruments components to avoid counterfeit risks. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or material changes that may affect long-term availability or specifications.

Supervisors Selection Notes

Select this component when a fixed 1.71 V threshold is required for low-voltage rail monitoring. The push-pull output eliminates the need for external pull-up resistors compared to open-drain variants. Consider the 10 ms/200 ms selectable delay for filtering noise during power-up sequences. Compare against TPS3838 series if open-drain output is preferred for wired-OR configurations. Ensure the 6 V maximum input rating aligns with the monitored supply voltage headroom.

Supervisors Part Context

This part belongs to the TPS383x family of NanoPower Supervisory Circuits from Texas Instruments. It shares core architecture with the TPS3836 and TPS3838 series, differing primarily in output type and threshold options. The E18 designation specifies the 1.71 V trip point, while DBVT denotes the SOT-23-5 thermal enhancement package. This family targets applications demanding minimal quiescent current and precise voltage monitoring in space-constrained designs.

Supervisors Replacement Considerations

TPS3836E18DBVRG4 is a lead-free version with identical electrical characteristics. TPS3838E18DBVT serves as a functional alternative but features an open-drain output instead of push-pull. Verify package compatibility and output drive requirements before substitution. No other direct pin-to-pin replacements are documented in public sources.
