UCC2946D Overview
Power management is mounted through 8 terminals. A Tube package is used to package the power management. In this IC power you will find 1 functions for you to refer to. There are a total of 1 channels on this supervisor, and they are arranged in a series. Please find attached 8-SOIC (0.154, 3.90mm Width) functions for your reference in this IC power. It is a IC power that shares many benefits with other products from the Simple Reset/Power-On Reset line. Packages are specified to have an average peak reflow temperature of 260. In a 1 supply voltage, the PMIC chip conducts. The mount is provided by Surface Mount. This power ic can be sub-categorized as Power Management Circuits. There are a total of 8 pins on power management. There are 8 pins on the supervisor. I should note that the minimum supply voltage (Vsup) for this IC management should be at least 2.1V, which is the minimum supply voltage that should be applied. Voltage (Vsup) shouldn't exceed 5.5V volts in this PMIC. Power management recommends the Surface Mount mounting type. You should set the supervisor's temperature during -40°C~85°C TA . When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. Supplied with a operating current of 10μA, this PMIC is capable of fully function as specified. It is always advisable to use UCC2946, the base supervisor number, when searching for similar PMICs from the manufacturer. In order to operate this power management, it requires 2.5/5V volts of power. At the most, voltage supervisor can work with a supply temperature of 18μA.
