Mount
Through Hole
Mounting Type

Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include: * Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side. * Surface-mount: Component is placed on the surface of the PCB and soldered in place. * Press-fit: Component is pressed into place on the PCB without soldering. * Socket: Component is inserted into a socket on the PCB, allowing for easy replacement. The mounting type is determined by factors such as the component's size, shape, and power requirements.

Through Hole
Package / Case

Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

Number of Pins

Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

Operating Temperature

Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

Series

Series, in the context of electronic components, refers to the arrangement of components in a circuit. When components are connected in series, they form a single path for current to flow through. The total resistance of a series circuit is the sum of the individual resistances of each component. Series connections are often used to control the flow of current in a circuit, as the total resistance can be adjusted by changing the number or type of components in the series.

Part Status

Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

Obsolete
Moisture Sensitivity Level (MSL)

Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

Operating Supply Current

Operating Supply Current is the amount of current drawn by an electronic component when it is operating under normal conditions. It is typically measured in milliamps (mA) or microamps (µA). The operating supply current is important because it can affect the power consumption of the component and the overall system. A higher operating supply current will result in higher power consumption, which can lead to overheating and reduced battery life.

Reset

Reset is an electronic component parameter that refers to the process of returning a device or system to its initial state. This can be done by applying a specific voltage or signal to the device, or by physically resetting the device. Resetting a device can be used to clear errors, restore default settings, or to start the device over from the beginning.

Description
The DS1816 EconoReset is a device that automatically restarts a microprocessor after a power failure. It maintains reset for 150ms after Vcc returns to an in-tolerance condition, reducing the need for discrete components. The device features a precision temperature-compensated voltage reference and voltage sensor, providing accurate power monitoring with tolerances of 5%, 10%, or 20%. It is available in low-cost TO-92 or space-saving SOT-23 packages and has an efficient open-drain output with an internal 5k2 pull-up resistor. The operating temperature range is -40°C to 85°C.
