Product details

Two-rail supervisor in a 6-pin SOT-23

It asserts an active-low, open-drain reset output when either monitored voltage falls below its threshold.

Adjustable thresholds and 125°C junction rating

Both monitored channels use adjustable/selectable thresholds, so the same base part number covers different supply combinations by changing the external resistor divider. The operating temperature range extends to 125°C junction — this is an industrial-grade part that can sit on a hot PCB near a regulator or in an outdoor enclosure without derating concerns. The open-drain output is active-low, which means it pulls to ground on a fault and requires a pull-up resistor to the monitored rail or the reset input of the downstream processor. This output topology allows wired-OR connections with other fault signals.

Frequently asked questions

Is TPS3780CDBVR equivalent to TPS3780QDBVR?

The TPS3780QDBVR is the automotive-qualified (AEC-Q100) variant of the same base supervisor. The CDBVR is the commercial/industrial temperature grade. Functionally they are the same, but the Q version carries automotive-specific qualification and may have different test flows. Confirm the temperature grade and qualification requirements of your BOM before substituting.
