UC1544L Product Details

UC1544L Overview


This voltage supervisor has a total of 20 mounting terminals that can be used for mounting. Please find attached 1 functions for your reference in this IC power. Power management consists of 1 channels, each of which can be used independently. Specifies a reflow peak temperature of NOT SPECIFIED for the package during reflow. IC management conducts at a voltage of 10V. A IC power such as this can be classified as a Power Management Circuits power management system. 20 pins are present in total in this power management. 20 pins are on the supervisor. In addition to the IC type POWER SUPPLY SUPPORT CIRCUIT, other types are also included in the power managment ic. To be able to work, this power management requires 4.5/40V volts of power. During operation, IC management can reach temperatures of up to 125°C. At a minimum, PMIC chip operates at a working temperature of -55°C.
