  "textContent": "A microelectromechanical sensor device (1) has a detection structure (66) and an associated electronic circuitry (2), configured to receive, when the device is powered, an external power supply voltage (VDD) and provided with a voltage regulator (8) generating a regulated voltage (VREG) and with at least one voltage domain (6) powered by the regulated voltage. The electronic circuitry has a power supply management core (10), always powered by the external power supply voltage and which controls the voltage regulator to selectively interrupt the power supply of the voltage domain to implement: a first power-down condition wherein the voltage regulator is disabled; and a second power-down condition wherein the voltage regulator is enabled to power the aforementioned voltage domain through the regulated voltage, the first and the second power-down conditions being associated with absence of data acquisition by the sensor device. The power supply management core automatically enables the first or second power-down condition upon a first power-on of the sensor device, as a function of a configuration signal (Sconf), programmable, for example, during a factory calibration step.",
