Product details

1.71V threshold supervisor for low-voltage rails

The TPS3126E18DBVT is a single-channel voltage supervisor from Texas Instruments, designed to monitor a 1.71V supply rail and assert a reset signal when the voltage drops below that threshold. The reset output is active-low, open-drain, so it can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail. This part is in the TPS3126 family, and the suffix denotes the 1.71V threshold — essential for tracking low-voltage core supplies in DSPs, MCUs, or FPGAs that run on 1.8V nominal rails.

100ms reset timeout and industrial temperature range

The reset timeout is 100ms minimum, which gives the downstream processor enough time to stabilize its internal state after power-up or a brown-out event. Packaged in a 5-pin SOT-23-5, this is a surface-mount part. The open-drain output means the pull-up resistor value sets the rise time into the reset input of the monitored IC.

Frequently asked questions

How can I order TPS3126E18DBVT or check availability?

The TPS3126E18DBVT is an active Texas Instruments part. Submit an RFQ with your target quantity and preferred delivery window; we source it through our distribution network and confirm pricing and lead time per order. No stock figures are published here.

Can TPS3126E18DBVT replace TPS3126E18DBVR?

The 'DBVT' and 'DBVR' suffixes typically indicate different packaging options (Tape & Reel vs. Cut Tape) for the same die in the same SOT-23-5 package. Electrically they are identical; the difference is the reel quantity and carrier format. Confirm with your distributor that the reel quantity matches your production needs.
