Product details

2.93V threshold supervisor for 3.3V rails

The active-low, open-drain output asserts reset when the monitored voltage drops below 2.93V and holds reset for a minimum of 20ms after the supply recovers above the threshold.

SOT-23-6 footprint and temperature range

Housed in a SOT-23-6 package with surface-mount termination, the part occupies minimal board area and suits dense PCB layouts where a single supervisor is needed per rail. The open-drain output requires an external pull-up resistor to the logic supply of the downstream device, typically 10 kΩ to 100 kΩ, and allows wired-OR connection with other open-drain reset sources.

Frequently asked questions

Does TPS3813K33DBVTG4 have an open-drain output?

Yes, the output is open-drain (open collector) and active-low, requiring an external pull-up resistor to the downstream logic supply.

Is TPS3813K33DBVTG4 RoHS compliant?

The part carries the 'G4' suffix indicating a RoHS-compliant, green (halogen-free) finish per Texas Instruments' standard green material declaration.

What is the reset timeout of TPS3813K33DBVTG4?

The reset timeout is a minimum of 20ms, ensuring the downstream device has sufficient time to stabilize after the supply returns above the threshold.
