Product details

2.93V threshold for 3.3V rails

The TPS3823A-33DBVT is a Simple Reset/Power-On Reset IC from Texas Instruments that monitors a single 3.3V supply rail. It asserts a reset signal (Active Low, push-pull output) when the supply drops to 2.93V — that's the undervoltage trip point, not the nominal rail voltage.

SOT-23-5 package and temp range

Housed in a SOT-23-5 package, this part is surface-mount and fits a standard 5-pin footprint. Lifecycle status is Active, meaning Texas Instruments is still producing it with no end-of-life notice. ROHS3 compliant.

Frequently asked questions

What is the exact threshold voltage of TPS3823A-33DBVT?

Designers need to confirm voltage monitoring level for their power rail.

Where can I buy TPS3823A-33DBVT in stock today?

Buyers need immediate availability to avoid production delays.

Is TPS3823A-33DBVT a direct replacement for TPS3823-33DBVT?

Engineers need to know compatibility when substituting parts in existing designs.

What is the typical price of TPS3823A-33DBVT per unit?

Sourcing buyers compare costs for BOM budgeting.

Can TPS3823A-33DBVT work with 3.3V systems?

Threshold is 2.93V, so it's intended for 3.3V rails; users must verify undervoltage detection.

Does TPS3823A-33DBVT have an equivalent from Maxim or other brands?

Engineers seek second sources for supply security or cost optimization.
