UCC3946PWG4 Product Details

UCC3946PWG4 Overview


This voltage supervisor has a total of 8 mounting terminals that can be used for mounting. Please find attached 1 functions for your reference in this IC power. Power management consists of 1 channels, each of which can be used independently. Please find attached TSSOP functions for your reference in this IC power. With power management, you get a lot of benefits that you won't find in other Simple Reset/Power-On Reset products. Specifies a reflow peak temperature of 260 for the package during reflow. By Surface Mount, IC management has been mounted. A IC power such as this can be classified as a Power Management Circuits power management system. 8 pins are present in total in this power management. 8 pins are on the supervisor. It is recommended that Vsup should not be less than 2V for this IC power. The maximum supply voltage (Vsup) is not to exceed 5.5V volts in this IC management. The power management's supply current is 10μA. To be able to work, this power management requires 2.5/5V volts of power. A maximum supply temperature of 18μA can be used. There are 1 elements featured in this power managment ic, which has been applied to a variety of applications.
