MIC2566 Micrel MIC2566 Single-Slot PC Card/CardBus Power Controller Preliminary General Description Features The MIC2566 single-slot PC Card / CardBus power controller Complete single-slot power switch solution is a V and V power switch matrix that supports 3.3V and No external components required CC PP 5V PC Card (PCMCIA) slot power supply pins. Output current limit and thermal shutdown Ultra-low power consumption The MIC2566 can switch PC Card slot V voltages between CC Compatible with standard PC Card logic controllers 0V (ground), 3.3V and 5.0V and V voltages between 0V PP Break-before-make switching (no transients) (ground), 3.3V, 5V, or high impedance at output currents of Digital V and V voltage selection up to 1A for V and 200mA for V . The MIC2566 features CC PP CC PP > 1A V output current per slot well-controlled voltage rise and fall times. Each MIC2566 CC > 120mA V output current per slot output voltage is switched by two digital inputs, typically PP 14-pin SOP and TSSOP package controlled from a separate PC Card logic controller. Pb-free SO package The MIC2566 is designed for efficient operation. In standby UL recognized, file 179633 (sleep) mode the device draws very little quiescent current, Applications typically only 0.3 A. The power controller includes thermal shutdown and protects itself and its PC Card ports with Single-slot PC Card power supply voltage switch current limiting. Full cross-conduction lockout protects the CardBus slot power supply control system power supplies. Data collection systems The MIC2566 is available in 14-pin SOP and TSSOP Machine control data input systems packages.
