The current • Analog Current Monitor Outputs sense topology provides both accurate current limits and independent setting of current limit and fast trip • -40°C to 125°C Operating Junction thresholds. Temperature The ORing control uses an external MOSFET to • QFN36 Package block reverse current when an input is shorted. Systems with closely matched supply voltages and APPLICATIONS feed networks can supply current from both supplies • ATCA Carrier Boards simultaneously. • AdvancedMC™ Slots The MONx output provides an accurate analog • Blade Servers indication of load current. • Base Stations The protection circuits may be used without blocking, • Configurable for and the blocking may be used without protection. – 1 Source, 2 Loads Internal connections prevent implementation of these – 2 Sources, 1 Load as four fully-independent functions. – 2 Sources, 2 Loads Figure 1.
