UC2544DWG4 Product Details

UC2544DWG4 Overview


As far as the mounting terminals of this voltage supervisor are concerned, it has 18 in total. 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 1 channels. In this IC management you will find SOIC functions for you to refer to. In order to ensure a good reflow performance, the package peak reflow temperature must be set at 260. A supply voltage of 10V is used to conduct the PMIC chip. A supply voltage of 1 is used to conduct the PMIC chip. Surface Mount is the one that mounts 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 4.5V 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. In order to maintain a stable supply current for the power management, 7mA is the recommended value. Besides the IC types mentioned above, the power management system also includes other types such as POWER SUPPLY SUPPORT CIRCUIT. The power management can work with a maximum supply temperature of 10mA.
