Product details

2.93V threshold supervisor for 3.3V rails

The minimum reset timeout of 15ms provides a de-glitch window that ignores short supply transients while ensuring the downstream device completes its reset sequence.

For procurement teams managing a live BOM line, the NRND flag means the window for last-time-buy (LTB) orders may open at any point. Qualifying a pin-compatible supervisor now avoids a forced redesign later.

SOT-23-5 footprint and automotive temperature grade

Housed in a SOT-23-5 package, the TPS3820-33QDBVRQ1 mounts on a standard 5-pin footprint. This is the same qualification tier used by Tier-1 automotive suppliers for ECU and ADAS modules.

Frequently asked questions

Is TPS3820-33QDBVRQ1 obsolete?

It is not yet fully obsolete, but TI recommends against using it in new designs. Existing production can continue while supply lasts, but a last-time-buy notice may be issued at any time.

Does TPS3820-33QDBVRQ1 have a push-pull output?

Yes, the reset output is push-pull (totem pole) with active-low polarity. No external pull-up resistor is needed on the reset line.
