Power Monitor, Control, and Protection

Analog Devices’ monitor, control, and protection family offers solutions for the analog and digital power management functions demanded by high performance systems. Monitoring functions include voltage supervision for reset generation, as well as ADC-based digital measurements of voltage, current, charge, power, energy, and temperature. For power control, devices can turn on/off power supply rails and also sequence, track, trim, and margin them with precision. Surge stoppers, hot swap, and ideal diode controllers protect against abnormal voltages and currents. Robust power over Ethernet (PoE) controllers allow up to 90 W of power to be managed and transferred between power sourcing equipment (PSE) and powered devices over low cost Ethernet cables. Our portfolio incorporates high accuracy, offers varying levels of functional integration, and features analog or digital configuration.

Analog Devices cable drop compensation technology provides tight load regulation solutions for long, highly resistive cables without requiring an additional pair of remote sense wires. Members of this portfolio continuously interrogate line impedance and correct power supply output voltage via a feedback loop to maintain steady voltage at the load regardless of current changes. Our devices also includes precision, high-side current sense products with current-mode output that are designed for controlling the output voltage of an adjustable power supply or voltage regulator. This can be used to compensate for drops in voltage at a remote load due to resistance in a wire, trace, or cable.
