Product details

Supervising the 3.3V rail – why that 2.64V threshold matters

The TPS3809L30DBVR is a single-channel voltage supervisor that holds the reset output low until the monitored supply rises above 2.64V and stays there for at least 120ms. That 2.64V trip point is set for a nominal 3.3V rail – it triggers when the supply drops about 20% below regulation, which is a common brownout detection window for 3.3V logic. If your processor needs a tighter threshold, this part will not work; but for a typical 3.3V MCU or FPGA bank, it is a standard fit.

We source it per RFQ – confirm your BOM quantity and target delivery window, and we will quote against the current market pricing and lead time.

Frequently asked questions

Is TPS3809L30DBVR RoHS compliant?

Yes, it is ROHS3 compliant per Texas Instruments' listing.

Can TPS3809L30DBVR be used with a 3.3V supply?

Yes – the 2.64V threshold is specifically set for a nominal 3.3V rail. It will assert reset when the supply drops below 2.64V, which is a typical brownout level for 3.3V logic.

When sourcing TPS3809L30DBVR, what is the closest functional alternative?

The TLV803EA29VDBZR is a similar simple reset supervisor from TI with an active-low output, but it uses an open-drain output (requires a pull-up resistor) and has a 130ms minimum timeout. The TPS3809L30DBVR's push-pull output eliminates that external resistor.
