Product details

What the STM6601AU2DDM6F actually does

The STM6601AU2DDM6F is a Smart ON/OFF Controller from STMicroelectronics' Smart Reset™ family — a supervisory IC that manages the power-on and power-off sequence of a battery-powered device with a single push-button input.

Where this part fits in a design

The 240ms minimum reset timeout gives the power supply time to stabilise before the processor starts executing code — a common requirement when the main regulator has a slow ramp or the battery is swapped under load. The 12-TDFN package (2x3mm) with an exposed pad keeps the board footprint small — the pad should be connected to the ground plane for thermal relief, though the part itself dissipates very little power.

Frequently asked questions

What does the 240ms reset timeout mean in practice?

The 240ms minimum timeout is the period the STM6601AU2DDM6F holds the reset line low after the monitored voltage rises above the 3.5V threshold. This gives the system power rail time to settle before the processor starts executing code — it prevents brown-out or glitch-related boot failures.

What package does the STM6601AU2DDM6F come in?

It is supplied in a 12-lead TDFN package measuring 2x3mm (supplier device package 12-TDFN). The package has an exposed thermal pad and is intended for surface-mount assembly.
