UCC3946NG4 Product Details

UCC3946NG4 Overview


There are 8 terminals connected to this power management, which makes it easy to mount. In terms of packaging, power management follows the Tube model. Please refer to this PMIC for 1 functions. There are a total of 1 channels on this supervisor, and they are arranged in a series. In this IC management you will find 8-DIP (0.300, 7.62mm) functions for you to refer to. This IC power shares lots of benefits with other Simple Reset/Power-On Reset products. A supply voltage of 1 is used to conduct the PMIC chip. The power management is mounted by Through Hole. The power management belongs to the Power Management Circuits subcategory. Taking into account all of the pins, this power management has a total of 8. There are 8 pins on the supervisor. IC management can only work with a supply voltage of 2V volts. This IC power should be powered by no more than 5.5V volts of supply voltage (Vsup). A Through Hole mounting type is recommended. Temperature setting for the supervisors should be 0°C~70°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. A similar IC managements number of the manufacturer can always be found by using UCC3946, the base power ics number. The voltage supervisor requires a power source of 2.5/5V volts in order to work correctly. At the most, voltage supervisor can work with a supply temperature of 18μA.
