MIC2560-1BWM: Dual-Slot PC Card Power Controller

The MIC2560-1BWM, designed and manufactured by Microchip Technology, is a versatile dual-slot PC Card power controller that is specifically engineered to manage the power requirements of two PC Card sockets compliant with the PCMCIA 2.1 and JEIDA 4.2 standards. This integrated circuit (IC) is an ideal solution for portable devices, such as laptops and PDAs, which require efficient power management for PC Cards, including memory cards, modems, and various other types of I/O cards.

One of the key features of the MIC2560-1BWM is its ability to independently control the VCC and VPP power supplies for each slot. This functionality allows the device to provide a wide range of output voltages necessary for different card types, ensuring compatibility and flexibility. The VCC outputs can be configured to deliver 3.3V, 5V, or x.xV, while the VPP outputs are capable of delivering 0V, 3.3V, 5V, or 12V, covering the full range of PC Card programming and operating voltages.

The IC incorporates several safety features, including current limiting, short-circuit protection, and thermal shutdown, to protect the system and the card from damage due to overcurrent conditions. Additionally, the MIC2560-1BWM offers low quiescent current, which is crucial for battery-powered applications where power conservation is paramount.

Furthermore, the MIC2560-1BWM is designed with an automatic low-power mode that minimizes power consumption when no card is inserted, and a card detection feature that enables the power controller to automatically 'wake up' and provide the necessary voltages when a card is inserted into either slot.

Available in a 28-pin SOIC package, the MIC2560-1BWM is compact and can be easily integrated into system designs. Its operation is specified over the full industrial temperature range, making it suitable for a wide array of environments and applications.

For designers and engineers looking for a reliable and efficient power management solution for dual-slot PC Card applications, the MIC2560-1BWM from Microchip Technology offers a feature-rich and dependable choice.
