Product details

Three-rail supervisor in a rework-friendly SOIC

It asserts both active-high and active-low reset outputs, push-pull, so it can drive the reset line of most microcontrollers or DSPs directly without an external pull-up. That is long enough to cover most bulk-capacitor ramp-up delays on a three-rail board.

Threshold voltages and reset timing

The fixed thresholds are 2.93V (for a 3.3V rail) and 4.55V (for a 5V rail), plus the adjustable input that can be set with a resistor divider to monitor a third rail anywhere in the supervisor's range. The reset timeout is specified as 140ms minimum, which means the reset outputs stay asserted for at least that long after all monitored voltages rise above their thresholds.

Active production, standard SOIC package

It comes in an 8-SOIC package (0.154", 3.90mm width), a common footprint that is straightforward to hand-solder or rework with a hot-air station.

Frequently asked questions

What are the threshold voltages for the TPS3307-33D?

The fixed thresholds are 2.93V and 4.55V, plus an adjustable input. That covers common 3.3V and 5V rails, with the third rail set by external resistors.

What is the reset timeout for the TPS3307-33D?

The reset timeout is 140ms minimum. The reset outputs stay low/high for at least that long after all monitored voltages cross their thresholds.

What package does the TPS3307-33D come in?

It is supplied in an 8-SOIC package (0.154", 3.90mm width), surface-mount, in tube packaging.

Is the TPS3307-33D a good fit for monitoring a 3.3V, 5V, and adjustable rail?

Yes. The fixed thresholds at 2.93V and 4.55V are directly suited for 3.3V and 5V rails, and the adjustable input lets you monitor a third rail at any voltage set by a resistor divider. The push-pull outputs eliminate external pull-ups.
