Hot-Swap Power Manager Controls Two AMCs

Dubbed the industry’s first single-chip, dual-slot hot swap manager for Advanced Mezzanine Cards (AMCs), the programmable TPS2359 hot swap controller performs all necessary power interface functions for two AMCs while requiring few external components. Enabling plug-and-play insertion and removal of AMCs, the device’s two 3.3V channels provide inrush control, over-current protection, and FET ORing control. In addition, two 12V channels provide the same functions using external FETs and sense resistors. The controller’s 3.3V current limits are set at the factory to AMC-compliant levels and the 12V current limits are programmable via external resistors. Also available, the TPS2358 controller provides dedicated output pins and configuration capabilities using external components. Prices for the TPS2359 and TPS2358 are $5 and $4 each/1,000, respectively. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
