MAX780CCNG

Power Management - Specialized Overview

The MAX780CCNG is a dual-slot PCMCIA analog power controller designed for notebook and palmtop computers. It provides power switching and status signals to control two Personal Computer Memory Card International Association (PCMCIA) Release 2.0 card slots. The device operates with dual voltage VCC supplies of 3.3V or 5V and generates VPP outputs at 0V, +5V, +12V, or high-impedance states. It features internal 1.6Ω VPP power switches and logic compatibility with industry-standard digital controllers such as the Intel 82365SL_DF. The component draws 130µA quiescent supply current, reducing to 3.5µA in shutdown mode.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'C' against the manufacturer's official documentation to confirm temperature range and package variations. Confirm that the SSOP-24 package dimensions match the target PCB footprint. Check for end-of-life status or active production updates directly from Analog Devices, as availability may vary by region and date.

Power Management - Specialized Selection Notes

Select this component when designing interfaces requiring analog control for dual PCMCIA slots. Ensure the system requires logic compatibility with Intel 82365SL_DF or similar standard controllers. Verify that the required VPP voltage levels align with the available 0V, +5V, +12V, or high-impedance options provided by the IC.

Power Management - Specialized Part Context

The MAX780 series serves as an analog power controller specifically for PCMCIA interfaces. The MAX780CCNG variant utilizes an SSOP-24 package. It complements digital controllers to form a complete interface solution with minimal external components. This family targets portable computing devices where space and power efficiency are critical constraints.
