UC3903DW Overview

As far as the mounting terminals of this voltage supervisor are concerned, it has 18 in total. Packaging is in the form of a Tube. In this IC power you will find 1 functions for you to refer to. Depending on the power managment ic you are looking at, you can find a total of 4 channels. In this IC management you will find 18-SOIC (0.295, 7.50mm Width) functions for you to refer to. There are many benefits that this IC power shares with other Multi-Voltage Supervisor products as well. In order to ensure a good reflow performance, the package peak reflow temperature must be set at 260. A supply voltage of 15V is used to conduct the PMIC chip. A supply voltage of 4 is used to conduct the PMIC chip. There is a subcategory called Power Management Circuits for this power management. In total, the power management has 18 pins in it. This power management system has 18 pins. A voltage (Vsup) that doesn't fall below 8V as the minimum supply voltage (Vsup) should be applied to this IC power in order to ensure its proper operation. The supply voltage (Vsup) should not exceed 40V volts in this IC power. The recommended mounting type for IC management is Surface Mount. The supervisors should be set to the following temperature: 0°C~70°C TA. While this power management is operating, it will output Open Drain or Open Collector as the output voltage. In order to maintain a stable supply current for the power management, 7mA is the recommended value. To find similar IC managements from the manufacturer, you can always search by UC3903. The power management can work with a maximum supply temperature of 18mA.
