UCC2946PW Overview


There are 8 terminals connected to this power management, which makes it easy to mount. A Tray package is used to package the power management. There are 1 functions included in this PMIC so that you can refer to them. This power management is made up of 1 channels which are available in a series format. To assist you, this PMIC includes 8-TSSOP (0.173, 4.40mm Width) functions. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. Packages are specified to have an average peak reflow temperature of 260. IC management conducts in a 1-voltage supply. Surface Mount mounts IC management. Power Management Circuits is a subcategory of this PMIC chip. In total, the power management has 8 pins in it. There are 8 pins on the supervisor. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 2.1V. During this IC power, the maximum supply voltage (Vsup) should not exceed 5.5V volts. Mounting type Surface Mount is recommended. The temperature of the supervisors should be set to this range: -40°C~85°C TA. The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. In order to maintain a stable supply current for the power management, 10μA is the recommended value. You can always use UCC2946, the base supervisor number, to search for similar PMICs of the manufacturer. To be able to work, this power management requires 2.5/5V volts of power. A maximum supply temperature of 18μA can be used with this power management.
