Suiting 240 VA system applications specified by UL60950, EN60950, and CSA1950, Micrel’s MIC2310 single-FET hot-plug controller targets blade server systems, base stations, servers, 12 V power distribution backplanes, enterprise switch networks, and telecommunications applications. The component incorporates high-side controller circuit for an external N-channel MOSFET, which has a user-programmable MOSFET drain current rate of change. The device employs dual-speed dual-level overcurrent fault protection with the primary detector response time being programmable via an external current sense resistor and the secondary detector having 2-bit user programmability and a <1 µs response time. A PWRGD signal indicates a valid output voltage, and the analog output signal is proportional to the steady-state load current. Pricing starts at $2.69 in 1,000 quantities.
