Product details

3.08V threshold for 3.3V rail monitoring

Its 3.08V threshold is set to monitor a 3.3V supply rail — when the rail drops below 3.08V, the active-low RESET output asserts, holding the system in reset until the supply recovers and the 120ms minimum timeout elapses.

Industrial temperature grade and tiny package

The 4-X2SON package measures 1x1 mm — a tiny footprint that saves PCB real estate but demands careful soldering. The exposed pad under the package aids thermal transfer; a solid via-in-pad layout under the pad helps keep the junction temperature down during continuous operation.

Frequently asked questions

Is TPS3831G33DQNT compatible with 3.3V systems?

Yes. The 3.08V threshold is designed to monitor a 3.3V supply rail. When the rail falls below 3.08V, the active-low RESET output asserts, preventing the system from operating on an undervoltage supply.

Does TPS3831G33DQNT require an external pull-up resistor?

No. The output is push-pull (totem pole), so it drives high and low without a pull-up. That saves one resistor per supervisor channel on the BOM.

What is the difference between TPS3831G33DQNT and TPS3831G33DRVT?

The two share the same die and threshold voltage. The suffix difference is package and reel format: DQNT is the 4-X2SON (1x1 mm) in Tape & Reel; DRVT is the same package but in a different reel quantity or tape orientation. Confirm the reel quantity on the distributor listing for your volume.
