General Description    
 
MIC2569 is designed to supply power to OpenCable"
systems and CableCARD" hosts. These CableCARDs
are also known as Point of Distribution (POD) cards.
MIC2569 supports both Single and Multiple stream cards
through a simple to control parallel interface. All voltage
switching is soft-start at turn-on, and break-before-make
when changing between different voltage supplies.
Built in current limiting protects all V
CC
 and V
PP
 output lines
of the host system from card faults and accidental short
circuits. MIC2569 provides a FAULT/ signal to indicate an
over-current or fault condition exists and is equipped with
internal thermal monitoring circuitry to protect the device
itself in the event of a sustained over-current condition.
MIC2569 is offered in a space saving 16 pin QSOP
packaging.
