Hot Swap Power Controllers Feature Flexible Fault Protection and Low Voltage Operation

SAN JOSE, Calif., April 11 /PRNewswire/ -- Highly integrated hot-swap power controllers for mass storage and data communications applications are available from Micrel Semiconductor (Nasdaq: MCRL - news), an industry leader in power management and high-speed communications integrated circuits.
Manufactured in 8-pin SOP and 16-pin QSOP packages, the MIC2582 and MIC2583 offer robust fault protection for circuits operating between 2.3V and 13.2V. They also provide 20V input surge protection, thereby eliminating the need for external protection circuits.
Both devices are designed to control an external N-Channel MOSFET switch for controlled inrush current during board insertion. The devices also provide fault isolation. Dual level fault protection provides filtering of high current surges that can occur in a system while still reacting rapidly to short-circuit faults, thereby preserving input supply regulation.
The MIC2583 offers a ``power-good'' output in addition to a power-on-reset (POR) output for programmable processors. The MIC2583R option offers auto-retry fault recovery.
``We designed the MIC2582 and MIC2583 to address applications where reliability and hot swap capability are a necessity, as they are in mass storage and telecommunication systems,'' said Larry Mazer, product marketing manager for Micrel. ``The level and speed of their fault protection are completely programmable, thereby making these devices easy to use without compromising performance,'' Mazer said.
The MIC2582BM and MIC2583BQS are available now for $1.95 and $2.28 respectively when purchased in 1,000-piece quantities.
