Product details

2.93V threshold supervisor for 3.3V rails

The TPS3705-33DGN is a single-channel voltage supervisor from Texas Instruments, monitoring a 3.3V supply rail with a threshold of 2.93V. When the monitored voltage drops below this threshold, the reset output (Active Low, Push-Pull) asserts and holds for a minimum of 140ms after the supply recovers. This part belongs to the Simple Reset/Power-On Reset category within the Power Management (PMIC / Gate Driver) line.

Industrial temp range and package

The base product number is TPS3705; other threshold variants in the same family share the same pinout, so a BOM change to a different voltage option is a direct drop-in if the threshold requirement shifts.

Frequently asked questions

How can I order TPS3705-33DGN or check availability?

The TPS3705-33DGN is an Active Texas Instruments part. Submit an RFQ with your target quantity; we source through our distribution network and confirm current pricing and lead time at quote time. The part ships in Tube packaging.

What is the reset timeout of TPS3705-33DGN?

The reset timeout is 140ms minimum. After the supply rises above the threshold, the reset output remains low for at least 140ms before releasing.

What are equivalents or alternatives to TPS3705-33DGN?

Functional alternatives include the TLV803EA29VDBZR (Active Low, Open Drain, 130ms timeout, -40°C to 125°C) and TLV803ED29DBZR (Active Low, Open Drain, 33ms timeout, -40°C to 125°C). Both are from Texas Instruments but have Open Drain output instead of Push-Pull, and different timeout and temperature ranges. Verify the output type and timing requirements before substituting.

Is TPS3705-33DGN pin compatible with TPS3705-30?

The TPS3705 family shares the same pinout across threshold variants. The TPS3705-30 would have a 3.0V threshold; the package and pin functions are identical, so it is a direct drop-in if the threshold requirement changes.

How to use TPS3705-33DGN in a circuit?

Connect the VDD pin to the 3.3V rail being monitored. The reset output (Active Low, Push-Pull) drives the processor reset input directly without an external pull-up resistor. A 0.1µF decoupling capacitor near the VDD pin is recommended.
