UCC3946PWTRG4 Product Details

UCC3946PWTRG4 Overview


This power management consists of 8 mounting terminals on which it can be mounted. As a reference, this IC management includes 1 functions for your convenience. This power management is made up of 1 channels which are available in a series format. As a reference, this IC power includes TSSOP functions for your convenience. As with other Simple Reset/Power-On Reset products, this IC management also offers a wide range of benefits. Packages are specified to have an average peak reflow temperature of 260. The power management is mounted by a Surface Mount-axis. The power management system can be categorized as a Power Management Circuits chip. Taking into account all of the pins, this power management has a total of 8. Pin count of the power management is 8. I should note that the minimum supply voltage (Vsup) for this IC management should be at least 2V, which is the minimum supply voltage that should be applied. There should be no more than 5.5V volts of maximum supply voltage (Vsup) in this power management. Supplied with a operating current of 10μA, this PMIC is capable of fully function as specified. To operate this power management, you will need at least 2.5/5V volts of power. The maximum supply temperature is 18μA. The power management system contains 1 elements and has been extensively used in all aspects of target applications.
