The LTC4411ES5#TRMPBF is an IC component designed by Linear Technology Corporation (now part of Analog Devices Inc.) This device is a high-performance power routing controller that provides automatic switchover between two power sources. It is offered in a small 5-pin TSOT-23 package, making it suitable for space-constrained applications. Now, let's delve into the key features and functionality of the LTC4411ES5#TRMPBF.
1. Power Source Selection:
The LTC4411ES5#TRMPBF allows seamless switching between two power sources, such as a primary power supply and a backup power supply. It employs an internal ideal diode controller architecture, ensuring minimal voltage drop during power source selection.
2. Ideal Diode Controller:
This component integrates an ideal diode controller circuitry that eliminates the need for bulky diodes or MOSFETs. It provides efficient power paths with ultra-low forward voltage drops during source selection and reverse current blocking.
3. Reverse Current Blocking:
The LTC4411ES5#TRMPBF protects the primary power source from reverse current flow during switchover. This feature prevents any disruption or damage to the primary supply caused by the backup power source.
4. Low Quiescent Current:
To minimize power consumption, this component features an ultra-low quiescent current draw from both input supplies. It ensures efficient utilization of power sources, particularly crucial in battery-powered applications, extending battery life
