Key Featrues
Extremely Low RDS(ON) NMOS Switches: The low on-resistance of the NMOS switches minimizes power loss, improving efficiency and reducing heat generation, which is critical for compact devices like bar-code readers and handi-terminals.
Controlled Rise and Fall Times: By managing the slew rate of switching transitions, this feature reduces electromagnetic interference (EMI) and ensures smooth operation, making it suitable for noise-sensitive environments.
Break-Before-Make Switching: This prevents short circuits during switching by ensuring one path is fully disconnected before another is connected, enhancing safety and reliability in PCMCIA applications.
Inrush Current Limited (Drives 150µF Loads): The ability to handle large capacitive loads without excessive inrush current protects the device and connected components, making it ideal for powering PCMCIA cards in portable computing devices.
Applications
Portable Device Power Switching: The LTC1472 is well-suited for portable devices like palmtop and pen-based computers, where efficient power management is critical. Its low RDS(ON) NMOS switches and inrush current limiting capabilities ensure reliable operation and extended battery life in handheld applications.
Bar-Code Reader Power Control: The LTC1472 is an excellent choice for bar-code readers, providing precise control over power delivery to PCMCIA interfaces. Its slew rate control and break-before-make switching ensure smooth transitions between power states, minimizing disruptions during scanning operations.
Handi-Terminal Power Distribution: The LTC1472 is ideal for handi-terminals, where it can manage power distribution to PCMCIA slots efficiently. Its compatibility with industry-standard controllers and ability to handle continuous 12V power without external components make it a reliable solution for industrial and commercial terminal applications.
