UCC3946D Product Details
UCC3946D Overview
Power management is mounted through 8 terminals. Tube-packaging is used. Power management is possible to find a series of 1 functions. Power management consists of 1 channels, each of which can be used independently. Please refer to power management for 8-SOIC (0.154, 3.90mm Width) functions. With power management, you get a lot of benefits that you won't find in other Simple Reset/Power-On Reset products. IC management is specified that the package peak reflow temperature should be 260. A supply voltage of 1 is used to conduct the PMIC chip. The mount is provided by Surface Mount. There is a subcategory called Power Management Circuits for this power management. Power management has a total of 8 pins. Power managment ic pin count is 8. IC management can only work with a supply voltage of 2V volts. The maximum supply voltage (Vsup) is not to exceed 5.5V volts in this IC management. Surface Mount is the recommended mounting type. This range of temperature should be set for the supervisors: 0°C~70°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. It is estimated that the voltage supervisor's supply current is 10μA. If you want to search for similar IC managements of this manufacturer, you can always refer to UCC3946, which is the base power ics number. The power management must be powered by 2.5/5V volts to function properly. A maximum supply temperature of 18μA can be used with this power management.
UCC3946D Features
Simple Reset/Power-On Reset type Minimum supply voltage of 2V 10μA operating supply current
UCC3946D Applications
There are a lot of Texas Instruments UCC3946D Voltage Supervisors applications.
