Abstract: A power supply device having a thermal insulation function includes a circuit board, and at least one heat-sensitive component and a plurality of heat-generating electronic components that are disposed on the circuit board and spaced apart from one another. The heat-generating electronic components include a transformer, an inductor, an integrated circuit, or a metal oxide semiconductor (MOS). A minimum distance between the heat-sensitive component and the heat-generating electronic components is 7 mm. A thermal insulation area is defined between the heat-sensitive component and the heat-generating electronic components, and none of the heat-generating electronic components is disposed within a 270° range of the thermal insulation area. The heat-generating electronic components are disposed outside the thermal insulation area to separate the heat-sensitive component from a heat source on the circuit board, such that a high temperature of the heat source has less influence on the heat-sensitive component.

Abstract: The present application discloses a power-on-reset circuit, which optimizes a hysteresis circuit and a reset signal generation circuit, and introduces a seventh PMOS transistor as a switch transistor to achieve the differentiation of control voltages at a gate end of a first NMOS transistor during powering-on and off. A voltage rise detection point is determined by a partial voltage of a resistor during powering-on, while a voltage fall detection point is directly determined by a power supply voltage during powering-off. Such differentiation may achieve a significant separation between the voltage rise detection point and the voltage fall detection point, reducing the voltage fall detection point to near a threshold voltage of the first NMOS transistor, and meeting the demand for a lower voltage fall detection point, which is consistent with a practical application of the power-on-reset circuit in an MCU.

Abstract: The present application discloses a multi-level voltage detector circuit. The voltage dividing circuit includes a first resistor string and a second circuit. The first resistor string is formed by n+1 voltage dividing resistors connected in series and outputs n divisional voltages. The second circuit provides n lower voltage dividing resistors. A kth lower voltage dividing resistor detects kth rise and fall detection points of a power supply voltage. When the kth rise detection point is detected, the second circuit provides a kth lower voltage dividing resistor and short-circuits the kth lower voltage dividing resistor. When the kth fall detection point is detected, the second circuit provides the kth lower voltage dividing resistor to a position between a second end of an nth voltage dividing resistor and the ground. As the value of k increases, the resistance of the kth lower voltage dividing resistor decreases.

Abstract: The proposed vibrational energy harvester comprises a frame (118), a mass (114) coupled to first and second primary flexures (110, 112) which are configured to flex and allow the mass to move in a first direction (130), a plurality of secondary flexures (120, 122) which are configured to flex and allow the mass to move in a different second direction (132), and a transduction assembly configured to convert movement of the mass and flexures into electrical energy, preferably of electrodynamic or piezoelectric type. Each of the primary flexures is coupled to a secondary flexure at a position spaced from the mass. The resonant frequency of torsional vibration modes can thereby be raised to a frequency higher than the frequency band of ambient vibrations, which effectively prevents the energy harvester from vibrating in undesirable torsional modes that would result in wear between components.
