ADM1270ACPZ-R2

Dispositivo de protección de entrada de alta tensión ADM1270

Analog Devices ADM1270 High Voltage Input Protection Device is a current-limiting controller that provides inrush current limiting and overcurrent protection for modular or battery-powered systems. When circuit boards are inserted into a live backplane, discharged supply bypass capacitors draw large transient currents from the backplane power bus as they charge. These transient currents can cause permanent damage to connector pins, as well as dips on the backplane supply that can reset other boards in the system. ADI ADM1270 is designed to control the inrush current, when powering on the system, via an external P-channel field effect transistor (FET). To protect the system from a reverse polarity input supply, there is a provision made to control an additional external P-channel FET. This feature prevents reverse current flow in case of a reverse polarity connection, which can damage the load or the ADM1270.

LM5060 High-Side Protection Controllers

Texas Instruments LM5060 High-Side Protection Controllers with Low Quiescent Current offers intelligent control of a high-side N-channel MOSFET during normal on/off transitions and fault conditions. The constant rise time of the output voltage results from the inrush current control. Both an Input UVLO (with hysteresis) and a programmable input OVP are provided, with an enable input offering a remote on or off control. The initial start-up V_GS fault detection delay time, the transition V_DS fault detection delay time, and the continuous over-current V_DS fault detection delay time is programmed from a single capacitor. The MOSFET is latched off until either the enable input, or the UVLO input is toggled low and then high when a detected fault condition persists longer than the allowed fault delay time.
