Microchip | MIC2569YQS

MIC2569YQS is designed to supply power from within the CableCARD™ host to the CableCARD™. Prior to release 2.0 of the CableCARD™ Interface Specification these cards were 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 VCC and VPP 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.
