Microchip Smart E-Fuse Devices

Smart E-Fuse Devices

Microsemi's SmartE-Fuse Devices are electronic fuses designed to protect power management circuits against voltage spikes and surges along with a wide selection of other value-added features. These additional features include fault monitoring via external pins or over an I2C bus, current monitoring outputs for use by ADCs, high-speed DC/DC regulators with I2C output voltage control, in addition to control of the currents during startup, hot-plug, and crowbar events. These devices complement our high-performance DC/DC regulators and controllers for today's commercial and industrial applications.
