General Description
The MIC2566 single-slot PC Card / CardBus power controller
is a V
5V PC Card (PCMCIA) slot power supply pins.
The MIC2566 can switch PC Card slot V
0V (ground), 3.3V and 5.0V and V
(ground), 3.3V, 5V, or high impedance at output currents of
up to 1A for V
well-controlled voltage rise and fall times. Each MIC2566
output voltage is switched by two digital inputs, typically
controlled from a separate PC Card logic controller.
The MIC2566 is designed for efficient operation. In standby
(sleep) mode the device draws very little quiescent current,
typically only 0.3 A. The power controller includes thermal
shutdown and protects itself and its PC Card ports with
current limiting. Full cross-conduction lockout protects the
system power supplies.
The MIC2566 is available in 14-pin SOP and TSSOP
packages.
