LTC1472CS#TRPBF

Overview

The LTC1472CS#TRPBF is a protected switching matrix designed for PCMCIA applications, integrating VCC and VPP switch functions within a single package. It operates with a supply voltage range of 0V to 12.6V and delivers a maximum output current of 1A per channel. The device features a typical on-resistance of 140mOhms and includes slew rate control to manage transient currents. Built-in fault protection mechanisms encompass fixed current limiting and over-temperature shutdown. The component is housed in a 16-lead narrow-body SOIC package suitable for surface-mount assembly.

Feature Summary

• Integrates dual protected switches for VCC and VPP power distribution
• Includes slew rate controlled output drivers to limit inrush current
• Provides comprehensive fault protection with current limiting and thermal shutdown

Applications

• PCMCIA card power management systems
• Laptop and portable computer peripheral power switching
• Protected high-side switch matrices for low-voltage digital loads

Procurement Notes

Verify the specific suffix #TRPBF confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the manufacturer designation remains Analog Devices Inc., formerly Linear Technology, to ensure component authenticity. Check for RoHS compliance status as indicated in the official datasheet documentation before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring isolated, protected power paths for legacy PCMCIA interfaces or similar low-voltage digital peripherals. The integrated current limiting and thermal protection simplify system design by removing external protection components. Ensure the input voltage range aligns with the target system's power rails and that the SOIC-16 footprint fits the available PCB area constraints.
