PMIC - OR Controllers, Ideal Diodes are widely applied in many fields. LTC4355CDE#PBF, which belongs to this category, can be used in the field of power control applications. This article will introduce its application field and working principle in detail.
In terms of its application field, the LTC4355CDE#PBF mainly focuses on the power control applications. It integrates the ORing MOSFETs and ideal diodes, helping to make the power supply design easy and reliable. By connecting two or more power supplies, it can provide the highest possible current output and also ensure that over-current or short-circuit condition is always be eliminated. Furthermore, it also can act as an ideal diode, which operates efficiently while reducing power dissipation. It is well-suited for computers, battery-powered systems, and many types of distributed power systems.
Besides, its working principle also serves as an important feature. It has a wide range input voltage from 2.75 to 20V. By applying this voltage to the gate of the integrated power FETs, the device can detect which of the power supplies is supplying the most current to the output. The LTC4355CDE#PFB uses a low-side MOSFET architecture to control the switch, which can be controlled by the logic level input and provide a constant current output. The output level is determined by setting the bias resistors between the logic pins and GND. Moreover, it can turn off the unused source and save possible power wastage.
All above stands for the application and working principle of the LTC4355CDE#PFB. In summary, this product works as an ORing MOSFET controller and ideal diode, mainly being used in power control applications. It has wide range input voltage, and its output can be controlled by setting the bias resistors. Its main advantages lie in its capability of higher current output and power saving.
