MAX6421US25 Product Details

MAX6421US25 Overview


There are 4 terminals connected to this power management, which makes it easy to mount. For your reference, this IC power includes a list of 1 functions. This power managment ic consists of 1 channels, each of which can be used independently. For your reference, this PMIC includes a list of SOT-143 functions. Specifies a reflow peak temperature of 260 for the package during reflow. IC management conducts in a 5V-voltage supply. The mount is provided by Surface Mount. Power Management Circuits is a subcategory of this PMIC chip. The total number of pins on this power management is 4. There are 4 pins on the supervisor. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 1V. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 5.5V volts. Among other features, IC power can be also taken advantage of [0], for instance. This supervisor includes other kinds of integrated circuits, such as POWER SUPPLY SUPPORT CIRCUIT as well as other kinds.
