• Integrates dual high-side switches for VCC and VPP control in a compact package
• Includes built-in current limiting and thermal shutdown protection circuits
• Features controlled slew rate to manage inrush current when driving capacitive loads

Applications

• PCMCIA card power management
• CardBus interface power distribution
• High-side load switching for portable electronics

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the component meets the required thermal and current specifications for the target application environment before integration.

Selection Notes

Select this component when dual independent high-side switching is required for low-voltage logic or memory cards. Consider the integrated protection features and soft-start capabilities as key advantages over discrete MOSFET solutions for space-constrained designs.

Part Context

This part belongs to the Neutron series of power switches from Analog Devices. It is specifically engineered for systems requiring reliable power sequencing and protection for peripheral interfaces like PCMCIA slots, combining driver and protection logic in one unit.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic replacements may lack integrated thermal or current protection.
