1 - Halogen Free
The term "Halogen Free" in electronic components refers to a specific characteristic of the materials used in the manufacturing of the component. Halogens are a group of elements that include fluorine, chlorine, bromine, iodine, and astatine. These elements are commonly used in flame retardants and other materials in electronics. However, the presence of halogens can pose environmental and health risks when the components are disposed of or recycled.Therefore, electronic components labeled as "Halogen Free" are manufactured without the use of halogenated materials. This designation indicates that the components do not contain any halogens, making them safer for the environment and human health. Halogen-free components are becoming increasingly popular in the electronics industry due to the growing awareness of environmental concerns and regulations regarding hazardous substances in electronic products.
Halogen Free - Supply Current-Max (Isup)
Supply Current-Max (Isup) refers to the maximum amount of current that an electronic component can draw from its power supply during operation. It represents the peak current demand of the device under normal operating conditions and is critical for ensuring that the power supply can adequately support the component's needs without risking damage or malfunction.

0.04mA - Min Reset Threshold Voltage
Min Reset Threshold Voltage refers to the minimum voltage level at which a device, such as a microcontroller or a voltage supervisor, can reliably reset its internal state. When the supply voltage drops below this threshold, the device initiates a reset process to clear the current execution state and restore it to a known initial condition. This parameter is critical for ensuring proper operation during power fluctuations, preventing unintended behavior from occurring due to insufficient voltage.
2.55V - Max Reset Threshold Voltage
Max Reset Threshold Voltage refers to the maximum voltage level at which an electronic component, such as a voltage regulator or a reset circuit, will reset or initialize itself. When the input voltage exceeds this threshold, the component typically enters a defined state, often resetting its output or operational mode. It is a critical specification to ensure reliable operation and prevent unexpected behavior in electronic devices. This parameter is important for design considerations in applications where voltage fluctuations or spikes may occur.
2.8V - Threshold Voltage
The threshold voltage is a critical parameter in electronic components, particularly in field-effect transistors (FETs). It refers to the minimum voltage required at the input terminal of the FET to turn it on and allow current to flow between the source and drain terminals. Below the threshold voltage, the FET remains in the off state, acting as an open switch. Once the threshold voltage is exceeded, the FET enters the on state, conducting current between the source and drain.The threshold voltage is a key factor in determining the operating characteristics of FETs, such as their switching speed and power consumption. It is typically specified by the manufacturer and can vary depending on the specific type of FET and its design. Designers must consider the threshold voltage when selecting FETs for a particular application to ensure proper functionality and performance.

During power up and power down, the UVLO function of the device has at least 0.1 V of hysteresis, but not more than 0.3 V. The UVLO function in power devices is a useful feature that enables robust system behavior across a wide range of operating conditions.
2.71V - Overvoltage Threshold
Overvoltages are all voltages that temporarily surpass the threshold value of the mains voltage. However, overvoltages can not only occur in the 230 V (normal household power supply voltage) mains, but can also reach the connected devices via telephone or aerial cables.
2.8V - Voltage - Supply (Max)
Voltage - Supply (Max) is a parameter in electronic components that specifies the maximum voltage that can be safely applied to the component for proper operation. This parameter is crucial for ensuring the component's longevity and preventing damage due to overvoltage conditions. Exceeding the maximum supply voltage can lead to component failure, reduced performance, or even permanent damage. Designers must carefully consider this parameter when selecting components and designing circuits to ensure reliable and safe operation within the specified voltage limits.
10V - Voltage - Supply (Min)
Voltage - Supply (Min) is a parameter in electronic components that specifies the minimum voltage required for the component to operate within its specified performance range. This parameter indicates the lowest voltage level that can be safely applied to the component without causing malfunctions or damage. It is crucial to ensure that the supply voltage provided to the component is equal to or higher than the specified minimum voltage to guarantee proper functionality and reliability. Failure to meet this requirement may result in erratic behavior, reduced performance, or even permanent damage to the component.

No - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
RoHS Compliant - Lead Free
Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.
