Frequently Asked Questions

What reset threshold does the TPS3839G33DBZR monitor?

The TPS3839G33DBZR is a fixed-threshold supervisor that monitors a 3.3 V supply rail through a single channel, asserting reset whenever the voltage drops below its factory-set 3.3 V trip point.

How is the TPS3839G33DBZR packaged for compact designs?

The TPS3839G33DBZR ships in a 3-pin SOT23 package, giving designers a tiny footprint for a single-channel 3.3 V voltage supervisor in battery-powered or space-constrained embedded boards.

Which products typically integrate the TPS3839G33DBZR supervisor?

Wearables, handheld instruments, and remote sensor nodes typically integrate the TPS3839G33DBZR's single-channel 3.3 V supply monitoring to trigger a reliable reset whenever the rail sags below 3.3 V.

Why is Pb-free compliance relevant when sourcing the TPS3839G33DBZR?

Because the TPS3839G33DBZR is manufactured as a Pb-free part, procurement teams building RoHS-compliant systems around this 3.3 V, single-channel supervisor can source it without needing a separate leaded variant.
