MIC2564A-0BSM Dual Slot PC Card Power Controller

The MIC2564A-0BSM is a high-performance dual-slot PC Card power interface switch designed by Microchip Technology. This integrated circuit (IC) is specifically engineered to provide power control solutions for two independent PC Card sockets, commonly used in notebook computers, docking stations, and other portable devices that support PCMCIA (Personal Computer Memory Card International Association) cards.

With its compact 16-pin small outline package (SOIC), the MIC2564A-0BSM is optimized for space-constrained applications. The device ensures efficient power distribution and protection by featuring independent 0V to 5.5V and 0A to 1A current-limited power switches for each slot. This enables the controller to supply VCC and VPP voltages required by PC Cards, including memory cards, modem cards, and other I/O devices.

One of the key advantages of the MIC2564A-0BSM is its built-in fault protection. It includes over-current, short-circuit, and thermal protection, which safeguards both the power controller and the PC Card from potential damage. Additionally, the device offers under-voltage lockout (UVLO) to ensure that the power is only turned on when a sufficient supply voltage is present, preventing malfunction at low voltages.

The power controller also features a low quiescent current, making it an energy-efficient choice for battery-powered applications. The MIC2564A-0BSM supports hot insertion and removal of PC Cards, which is critical for user convenience and the flexibility of the host device.

For design engineers, the MIC2564A-0BSM simplifies the implementation of PC Card power control in their systems. Its industry-standard pinout and easy-to-use interface enable seamless integration into a wide range of designs without the need for complex programming or additional components.

Overall, the MIC2564A-0BSM from Microchip Technology is a reliable and robust solution for managing power requirements in dual-slot PC Card applications, ensuring both performance and protection.
