Analog Devices LTC4412IS6#TRMPBF PowerPath Controller

The ​LTC4412IS6#TRMPBF​ is a ​PowerPath controller​ designed for ​ideal diode functionality​ in power management applications. It integrates a ​P-channel MOSFET​ to replace traditional diodes, reducing forward voltage drop and power loss. The device supports ​2:1 input selection​ and operates over a ​2.5V to 28V input range, making it ideal for ​redundant power systems, ​battery backup solutions, and ​multi-source power selection. With a ​TSOT-23-6 package​ and RoHS compliance, it is suitable for compact, low-power designs.

​Key Features:​​

• ​Ideal Diode Functionality: Low forward voltage drop (typically <50mV at 1A) to minimize power loss.
• ​2:1 Input Selection: Automatically switches between two power sources (e.g., main power and battery) based on priority.
• ​Wide Operating Voltage: Supports input voltages from 2.5V to 28V, with output voltage up to 36.3V.
• ​Low Power Consumption: Quiescent current of 15µA in normal operation.
• ​Fast Switching: Turn-on time of 110µs and turn-off time of 13µs for seamless power transitions.
• ​Protection Features: Overvoltage, undervoltage lockout, and reverse current protection.
• ​Compact Packaging: TSOT-23-6 form factor for space-constrained applications.

​Applications:​​

• ​Redundant Power Systems: Ensures continuous operation by switching to backup power in case of primary source failure.
• ​Battery Backup Systems: Automatically selects between AC adapter and battery to maintain device functionality.
• ​Portable Devices: Optimizes power usage in smartphones, tablets, and wearable devices.
• ​Industrial Equipment: Provides reliable power management in PLCs, motor controllers, and medical instruments.
