Product details

2.93V threshold supervisor for 3.3V rails

The TPS3823A-33DBVR is a Texas Instruments Simple Reset/Power-On Reset IC designed to monitor a single 3.3V supply rail. Its 2.93V threshold triggers an active-low reset when the supply dips below that level, protecting downstream logic from brownout or power-up glitches.

Industrial temperature range and package fit

The SC-74A / SOT-753 package is a 5-pin SOT-23 footprint. The 0.95 mm pin pitch breaks out easily on a two-layer board — no need for a four-layer stack just for the supervisor.

Frequently asked questions

Can the TPS3823A-33DBVR replace the TPS3823-33?

The base product number is TPS3823, and the 'A' suffix typically indicates a minor revision or improved specification. The TPS3823A-33DBVR is the current active variant. Pinout and function are the same — confirm the threshold voltage and timeout match your BOM requirement before substituting.

What is the reset timeout of the TPS3823A-33DBVR?

The reset timeout is 120ms minimum. This is the duration the reset output stays low after the supply rises above the threshold.

Is the TPS3823A-33DBVR active low?

Yes — the reset output is Active Low. The output asserts low when the monitored voltage falls below the threshold and releases high after the timeout period.
