CAT809LEUR-T Product Details

CAT809LEUR-T Overview


As far as the mounting terminals of this voltage supervisor are concerned, it has 3 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 SOT-23-3 functions for you to refer to. In order to ensure a good reflow performance, the package peak reflow temperature must be set at 240. A supply voltage of 5V is used to conduct the PMIC chip. Surface Mount is the one that mounts power management. In total, the power management has 3 pins in it. This power management system has 3 pins. A voltage (Vsup) that doesn't fall below 1.2V 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 5.5V volts in this IC power. In order to maintain a stable supply current for the power management, 8μA 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 system contains 1 elements and has been extensively applied in various target applications.
