UC3903DWTR Overview

This voltage supervisor has a total of 18 mounting terminals that can be used for mounting. Packaged in the form of a Tape & Reel (TR), power management is easy to use. Please find attached 1 functions for your reference in this IC power. Power management consists of 4 channels, each of which can be used independently. Please find attached 18-SOIC (0.295, 7.50mm Width) functions for your reference in this IC power. With power management, you get a lot of benefits that you won't find in other Multi-Voltage Supervisor products. Specifies a reflow peak temperature of 260 for the package during reflow. IC management conducts at a voltage of 15V. Power management conducts at a voltage of 4. A IC power such as this can be classified as a Power Management Circuits power management system. 18 pins are present in total in this power management. 18 pins are on the supervisor. It is recommended that Vsup should not be less than 8V for this IC power. The maximum supply voltage (Vsup) is not to exceed 40V volts in this IC management. In this case, Surface Mount is the recommended mounting type. The temperature of the supervisors should be set to this range: 0°C~70°C TA. As this power managment ic operates, it is able to produce an output voltage of Open Drain or Open Collector. The power management's supply current is 7mA. To find similar IC managements from the manufacturer, you can always search by UC3903. A maximum supply temperature of 18mA can be used.
