Product details

2.63V threshold, 120ms timeout — active-low push-pull supervisor

The TPS3831L30DQNR is a single-channel voltage supervisor from Texas Instruments, monitoring a 2.63V threshold rail with an active-low, push-pull output. The 120ms minimum reset timeout ensures the downstream processor sees a full reset pulse before startup, covering the typical 100ms requirement with margin. This is a Simple Reset/Power-On Reset type — no adjustable delay or manual reset input.

Industrial temp grade and 1mm² package

Compared to the TLV803EA29VDBZR (open-drain output, 130ms timeout, -40°C to 125°C), the TPS3831L30DQNR's push-pull output saves the pull-up resistor, but the TLV803 offers a wider temperature range and a lower 2.93V threshold option. The TPS3831L30DQNR's 2.63V threshold is the right fit for a 2.7V or 2.8V rail — confirm your supply tolerance against the 2.63V min before committing.

Frequently asked questions

What is the reset timeout and threshold voltage of TPS3831L30DQNR?

The reset timeout is 120ms minimum. The voltage threshold is 2.63V, which monitors a single rail — typically a 2.7V or 2.8V supply. The output is active-low push-pull, so no external pull-up resistor is needed.

Is TPS3831L30DQNR equivalent to TPS3831L30DBVR?

Both parts share the same base number (TPS3831) and electrical ratings — 2.63V threshold, 120ms timeout, push-pull output. The difference is the package: the DQNR suffix is 4-X2SON (1x1), while the DBVR suffix is SOT-23-5. Confirm your PCB footprint before substituting.
