UC3903DW

UC3903DW Overview

Power management is mounted through 18 terminals. Tube-packaging is used. In this IC power you will find 1 functions for you to refer to. There are 4 channels on this power managment ic that can be found in a series. For your reference, this PMIC includes a list of 18-SOIC (0.295, 7.50mm Width) functions. There are a lot of similarities between this IC management and other Multi-Voltage Supervisor products. Specifies a reflow peak temperature of 260 for the package during reflow. The supervisor is always powered by a 15V volt supply. When a supply voltage of 4 is applied to the power ic, it conducts. There is a subcategory called Power Management Circuits for this power management. In total, IC powers are 18 pins on the board. Power managment ic pin count is 18. A voltage (Vsup) that doesn't fall below 8V as the minimum supply voltage (Vsup) should be applied to this IC power in order to ensure its proper operation. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 40V volts. Mounting type Surface Mount is recommended. This range of temperature should be set for the supervisors: 0°C~70°C TA. As a result of this supervisor's operation, the output voltage is Open Drain or Open Collector. There is a supply current of 7mA for the power management. For similar manage ics search of the manufacturer, you can always refer to UC3903, the base PMIC number. At most, voltage supervisor can operate at a supply temperature of 18mA.
