Product details

2.93V threshold supervisor with push-pull reset

It is designed for systems where a clean, glitch-free reset is critical during power-up, brown-out, or momentary supply dips. The reset output is active-low and push-pull, meaning it can sink or source current directly to the MCU reset pin without an external pull-up resistor.

60ms reset timeout — why it matters for boot reliability

A timeout shorter than the supply ramp time risks brown-out on every power cycle; 60ms is a common sweet spot for MCU-based designs with ceramic bypass caps and moderate load capacitance. The part monitors a single voltage rail, so it is a good fit for single-supply MCUs or as the primary supervisor in a multi-rail system where the other rails are sequenced from the main supply.

The 8-VSSOP package (3.00 mm width) is a small footprint that reflows well and is inspectable under a microscope — the 0.65 mm pitch is hand-solderable with a fine tip if needed. Surface-mount in an 8-TSSOP or 8-MSOP footprint — the 8-VSSOP supplier device package is the same mechanical outline. The exposed pad is not present on this package, so rework is straightforward: hot air at 290°C for 20 seconds lifts the part cleanly without cooking adjacent components.

Frequently asked questions

Does TPS3620-33DGKR have a push-pull output and active-low reset?

Yes. The reset output is active-low and push-pull (totem pole), so it can drive the MCU reset pin directly without an external pull-up resistor.
