Micrel Inc., is a leading manufacturer of IC solutions for the worldwide analog, Ethernet and high bandwidth markets. The Company's products include high performance analog, power, advanced mixed-signal and radio frequency semiconductors; high speed communication, clock management, Ethernet switch and physical layer transceiver integrated circuits. These products address a wide range of rapidly growing end markets including cellular handsets, portable and enterprise computing, enterprise and home networking, wide area and metropolitan area networks and industrial equipment.

A switch is used to connect and disconnect electric circuits at will. Switches cover a wide range of types, from subminiature up to industrial plant switching megawatts of power on high voltage supply and distribution lines. In applications where multiple switching options are required, mechanical switches have long been replaced by electronic switching devices which can be automated and intelligently controlled. A switch can also be referred to as a "gate". In the philosophy of logic, operational arguments are represented as logic gates. The use of electronic gates to function as a system of logical gates is the fundamental basis for the computer.

MIC2569YQS TR 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.
