UCC2946PWTRG4 Product Details

UCC2946PWTRG4 Overview


As far as the mounting terminals of this voltage supervisor are concerned, it has 8 in total. A Tape & Reel (TR) package is used to package the power management. In this PMIC, you can find 1 functions for your reference. On this supervisor, there is a series of 1 channels that can be found. In this PMIC, you can find 8-TSSOP (0.173, 4.40mm Width) functions for your reference. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. Specifies a reflow peak temperature of 260 for the package during reflow. A supply voltage of 1 is used to conduct the PMIC chip. The power management is mounted by a Surface Mount-axis. It is possible to subcategorize this power ic as a Power Management Circuits chip. Power management has a total of 8 pins. This power management system has 8 pins. IC management can only work with a supply voltage of 2.1V volts. This IC power should be powered by no more than 5.5V volts of supply voltage (Vsup). Surface Mount mounting is recommended. It is recommended to set the supervisor's temperature to this range: -40°C~85°C TA. During normal operation, this power managment ic can generate Push-Pull, Totem Pole of output voltage. As far as the supply current of the power management is concerned, it is 10μA. To find similar IC managements from the manufacturer, you can always search by UCC2946. The voltage supervisor requires a power source of 2.5/5V volts in order to work correctly. At most, voltage supervisor can operate at a supply temperature of 18μA.
