Product details

Two-rail watchdog for automotive power sequencing

The open-drain output lets multiple supervisors share a common pull-up, which is handy when you're sequencing several rails on an automotive ECU.

Setting the trip points for a multi-rail system

The voltage thresholds are adjustable via external resistor dividers, so you can set the monitoring points to match your specific supply rails — 3.3 V, 5 V, 1.8 V, or any other voltage the divider ratio supports. This flexibility means the same base part number covers different BOM configurations without a custom OTP variant. The SOT-23-6 package keeps the footprint small — six pins in a 2.9 mm × 1.6 mm body — which fits tight layouts on multilayer automotive PCBs where every square millimeter counts.

The base product number is TPS3780, which covers the full family of adjustable-threshold supervisors. The QDBVRQ1 suffix denotes the SOT-23-6 package and the automotive (Q1) grade.

Frequently asked questions

What is the difference between TPS3780AQDBVRQ1 and the base TPS3780?

The base TPS3780 without the Q1 suffix is the commercial/industrial grade. Functionally they are the same dual-voltage supervisor with adjustable thresholds and open-drain output, but the Q1 version is the one to specify for automotive or high-reliability industrial designs.

What is the TPS3780AQDBVRQ1's reset output type?

The reset output is active-low, open-drain. This means it pulls low when a monitored voltage drops below threshold, and requires an external pull-up resistor to the reset rail. The open-drain configuration allows wired-OR connections with other supervisors or reset sources.

How many voltages does the TPS3780AQDBVRQ1 monitor?

It monitors two independent voltages. Each channel has its own adjustable threshold set by external resistor dividers, so you can supervise two different supply rails — for example, a 3.3 V core rail and a 5 V I/O rail — with a single supervisor IC.
