Product details

Dual-rail supervisor in a tiny SON

The open-drain output lets you pull up to any logic voltage the downstream MCU or FPGA needs — no level translator required.

Two monitored rails, one small footprint

Monitoring two voltages in a single 6-SON (1.45x1 mm) package saves board space compared to using two separate reset ICs. The adjustable threshold per channel gives flexibility for non-standard rail voltages. The active-low, open-drain output is the standard interface for most processor reset inputs — no inversion or extra logic needed.

Frequently asked questions

What is the reset output type of TPS3780BDRYT?

The reset output is active-low, open-drain or open-collector. This means the output pulls low when a fault is detected, and you can connect a pull-up resistor to any voltage up to the absolute maximum rating.

How many voltages does TPS3780BDRYT monitor?

It monitors two independent voltages. Each channel has an adjustable threshold, so you can set the trip points to match your specific rail voltages.

Is TPS3780BDRYT RoHS compliant?

Yes, it is ROHS3 compliant.

When sourcing TPS3780BDRYT, what's the closest functional second-source?

The TLV803 series (e.g., TLV803EA29VDBZR, TLV803ED29DBZR) is a simple reset/power-on reset family with active-low, open-drain output and similar temperature range. However, the TLV803 monitors a single voltage and has a fixed reset timeout, while the TPS3780BDRYT monitors two voltages with adjustable thresholds. They are not pin-compatible substitutes; evaluate the differences before cross-referencing.
