LTC4421CG#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4421CG#TRPBF is a high-power prioritized PowerPath controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 28V and supports up to 2A load current. The device features a low-loss ideal diode and load switch topology, utilizing an SSOP-28 package for surface-mount installation. Key electrical characteristics include a quiescent current of 50µA and a forward voltage drop of 20mV at 2A. It provides comprehensive protection against reverse current, overcurrent, and thermal overload conditions.

OR Controllers, Ideal Diodes Feature Summary

• Integrates a low-loss ideal diode and load switch for seamless power path management
• Provides prioritized power selection between two independent input sources
• Includes built-in protections for reverse current, overcurrent, and thermal events

OR Controllers, Ideal Diodes Applications

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix 'TRPBF' indicates tape-and-reel packaging with lead-free composition. Confirm the 'C' grade denotes commercial temperature range operation. Ensure compatibility with the required SSOP-28 footprint during procurement planning. Cross-reference the datasheet revision to confirm pinout consistency before finalizing orders.

OR Controllers, Ideal Diodes Selection Notes

Select this component when dual-input power redundancy is required with minimal voltage drop. Consider the 2A current limit and 28V maximum input rating for system design. Evaluate the need for external components for soft-start or fault indication if not integrated. Compare against lower-current alternatives if system loads are significantly smaller than 2A.
