Overview
The LTC1471CS#TRPBF is a single PCMCIA-protected power switch manufactured by Analog Devices Inc. It operates with an input voltage range of 3.3V to 5V and is housed in an 8-pin SOIC package. The device features built-in current limit protection and thermal shutdown capabilities to safeguard connected loads. It utilizes an N-channel output configuration for high-side switching applications.
Feature Summary
- Single channel PCMCIA-compliant power switch
- Integrated current limit and thermal shutdown protection
- High-side N-channel output configuration
Applications
- PCMCIA card slot power management
- Portable computer peripheral power switching
- Battery-powered device load control
Procurement Notes
Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix #TRPBF indicates tape-and-reel packaging. Ensure compatibility with system voltage requirements before integration. Request original manufacturer documentation to validate specifications against counterfeit risks.
Selection Notes
Select this component for applications requiring strict PCMCIA compliance and compact footprint. The 8-pin SO package suits space-constrained designs. Evaluate thermal performance under maximum load conditions due to integrated protection features. Consider the fixed 3.3V/5V input range when designing power supply rails.
Part Context
This part belongs to the LTC1471 series of protected switches designed for portable electronics. It complements dual-switch variants like the LTC1472, offering a simplified solution for single-rail applications. The series addresses the need for reliable power sequencing and protection in mobile computing environments.
Replacement Considerations
Direct substitutes include other PCMCIA-compliant switches from Analog Devices such as the LTC1472 for dual-channel needs. Verify pinout compatibility and electrical ratings before substitution. Cross-reference with generic high-side switches only if interface and protection features align.
