UCC3946PWTR Product Details

UCC3946PWTR Overview


There are 8 terminals on this power management that allow it to be mounted. This power ic is packaged in a way that looks like a Tape & Reel (TR). Power management is possible to find a series of 1 functions. There are a total of 1 channels on this supervisor, and they are arranged in a series. For your reference, this PMIC includes a list of 8-TSSOP (0.173, 4.40mm Width) functions. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. As specified in the package specification, the peak reflow temperature of the package is set at 260. Power management conducts at a voltage of 1. The mount is attached to Surface Mount. There is a subcategory called Power Management Circuits for this power management. In total, the power management has 8 pins in it. Power managment ic pin count is 8. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 2V. The supply voltage (Vsup) should not exceed 5.5V volts in this IC power. The mounting type of the supervisors is Surface MountThis power management is the recommended temperature range for the supervisors: 0°C~70°C TA. When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. The supply current of the power management is 10μA. To find similar IC managements from the manufacturer, you can always search by UCC3946. It is necessary to have 2.5/5V volts of power in order for this voltage supervisor to operate. If you want to work with PMIC chip, you will need to supply PMIC chip with a temperature at least of 18μA.
