UCC2946DTR Overview


This voltage supervisor has a total of 8 mounting terminals that can be used for mounting. In terms of packaging, power management follows the Tape & Reel (TR) model. Power management is possible to find a series of 1 functions. There are 1 channels on this power managment ic that can be found in a series. Please refer to power management for 8-SOIC (0.154, 3.90mm Width) functions. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. Specifies a reflow peak temperature of 260 for the package during reflow. Power management conducts at a voltage of 1. Power management is included in the Surface Mount mount. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. 8 pins are present in total in this power management. 8 pins are on the supervisor. Supply voltage (Vsup) should be at least 2.1V for this power management. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 5.5V volts. A Surface Mount mounting type is recommended. The temperature of the supervisors should be set to this range: -40°C~85°C TA. When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. The power management's supply current is 10μA. To find similar IC managements from the manufacturer, you can always search by UCC2946. This power management requires 2.5/5V power to work. At most, voltage supervisor can operate at a supply temperature of 18μA.
