Product details

Supervisor IC for 1.8V Rails

The Texas Instruments TPS3831G18DQNT is a simple reset/power-on reset supervisor that monitors a single voltage rail with a 1.67V threshold, ideal for 1.8V supply supervision in embedded systems. It asserts an active-low, push-pull reset output for a minimum of 120ms after the monitored voltage rises above the threshold, ensuring the processor or FPGA starts from a known state.

Housed in a 4-X2SON (1x1 mm) supplier device package, this supervisor is a surface-mount component. The small footprint suits space-constrained designs like portable instruments or compact control modules.

Frequently asked questions

Is TPS3831G18DQNT available via RFQ confirmation?

Stock levels are not published here. Submit an RFQ to receive real-time availability and lead-time confirmation from our sourcing desk.

Is TPS3831G18DQNT obsolete?

No, TPS3831G18DQNT is Active in production status per the manufacturer's lifecycle record. There is no discontinuation notice on file.

What is a replacement for TPS3831G18DQNT?

A functional alternative is the TLV803EA29VDBZR, which also provides an active-low reset but with an open-drain output, a 130ms timeout, and a wider temperature range of -40°C to 125°C. Verify the output type and threshold voltage (2.93V for that part) against your design before substituting.
