UCC3946DTR Product Details

UCC3946DTR Overview


This voltage supervisor has a total of 8 mounting terminals that can be used for mounting. There is a Tape & Reel (TR)-packaging method applied to IC management. As a reference, this IC management includes 1 functions for your convenience. On this supervisor, there is a series of 1 channels that can be found. Please find attached 8-SOIC (0.154, 3.90mm Width) functions for your reference in this IC power. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. During the reflow process, a peak temperature of 260 is specified for the package. Power ics operate at 1 supply voltages. Using Surface Mount, IC management is mounted. There is a subcategory called Power Management Circuits for this power management. There are a total of 8 pins on power management. This power management system has 8 pins. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 2V. The maximum supply voltage (Vsup) in this PMIC should not exceed 5.5V volts. The recommended mounting type is Surface Mount. This power management is the recommended temperature range for the supervisors: 0°C~70°C TA. The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. For this power management, there is an 10μA volt supply current. It is always advisable to use UCC3946, the base supervisor number, when searching for similar PMICs from the manufacturer. A power supply of 2.5/5V watts is required for the operation of this power management. A maximum supply temperature of 18μA can be used with this power management.
