MIC2569
CableCARD™ Power Switch
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.
Data sheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
