Typical applications for the eFuses are HDD/SSD arrays and servers, industrial and network hot-swap boards, and devices supplied by separate external AC adapters. Unlike conventional circuit protections, the eFuse offers much faster and accurate intervention, without requiring replacement after actuation. On STEF01, a fully programmable universal electronic fuse, the mode can be set by the user via the Auto pin.

(The fault status is signaled by the eFuse to the system controller by means of a Fault pin.) The former type can be reset by the user via the enable pin, the latter autonomously try to re-arm after a fault. The startup time is adjustable by changing a soft start capacitor.Īmong ST's eFuses, certain devices operate in latch-off or auto-retry mode after a fault event. This function is very useful in applications where a single power supply serves several loads connected to the same rail, such as HDD arrays and servers. About 55 of breast cancers express low levels of HER2. The aspects such as heterogeneity and long-term outcomes, heterogeneity and anti-HER2 therapies are also elaborated in the module. The author also tackles unresolved issues of heterogeneity. The overload current limit can be programmed by means of an external resistor.Īn input overvoltage clamp function is available in the majority of ST's eFuses, therefore the load can also be protected against power supply regulation failure leading to input voltage excursion.Īt turn-on, during power hot-plug or hot swapping of boards, the eFuse ramps up the output voltage in a linear and controlled way, which prevents a high inrush current flowing from the power source to the load, consequently avoiding power supply overload. HER2 testing is optimised to guide treatment decisions for the use of classical anti-HER2 therapies. If the anomalous overload condition persists, the device goes into an open state, disconnecting the load from the power supply. When an overload condition occurs, the device limits the output current to a safe value defined by the user. In terms of economics or the stock market, it affects the earnings of a company or even the entire economy as a.

When connected in series to the main power rail, an eFuse operates like a standard fuse with the ability of detecting and quickly reacting to overcurrent and overvoltage conditions. A driver is a factor that has a material effect on the activity of another entity. This disambiguation page lists articles associated with the title Low side. the Internet), in the context of air-gapped computer networks. Housed in small plastic packages, such as DFN and Flip-chip, they integrate a control circuit and a power switch with low on-resistance, connecting the input port to the load. Low side or lowside can refer to: A public computer network (e.g. Low Dropout (LDO) Linear Regulators (64)ĮFuses, or electronic fuses, are integrated circuits that can replace larger conventional fuses or other protection devices such as resettable polymeric fuses.Ballast Control ICs for Fluorescent Lamps (4).Power breakers and other Hot-swap ICs (3).

Energy Harvesting and Solar Charging ICs (2).Multi-Output Controllers and Regulators (8).Synchronous Rectification Controllers (7).This control scheme is the same as with single MOSFETs, making it easy to replace individual MOSFETs. The low side switch operates by applying an input voltage to the gate and connecting the MOSFET Source to ground. IPDs incorporate a high side switch for the upper circuit and a low side switch for the lower circuit with respect to external loads, utilizing a circuit design optimized for each location.Īs shown in the figure at left below, in a circuit where various loads are connected to a single power supply voltage, such as in a vehicle where the battery voltage is fixed and body connected to ground, the output can easily become grounded, making a high-side switch more suitable for detecting abnormal conditions such as ground faults.Ĭonversely, low side switches are ideal for circuits in which loads are placed at various power supply voltages as shown in the figure at right below. Usage examples for high side and low side switches High Side and Low Side Switches High Side/Low Side DriveĪ semiconductor switch placed in the upper circuit with respect to an external load is referred to as high-side drive (power supply side), and when mounted in the lower circuit is called low side drive (ground side).
