UC2903DW Product Details

UC2903DW Overview


As far as the mounting terminals of this voltage supervisor are concerned, it has 18 in total. There is a Tube-packaging method applied to IC management. As a reference, this IC management includes 1 functions for your convenience. There are 4 channels on this power managment ic that can be found in a series. There are 18-SOIC (0.295, 7.50mm Width) functions included in this PMIC so that you can refer to them. It is a IC power that shares many benefits with other products from the Multi-Voltage Supervisor line. As specified in the package specification, the peak reflow temperature of the package is set at 260. When a supply voltage of 15V is applied to the power ic, it conducts. Power management conducts at a voltage of 4. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. Taking into account all of the pins, this power management has a total of 18. Pin count of the power management is 18. It is recommended that Vsup should not be less than 8V for this IC power. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 40V volts. In this case, Surface Mount is the recommended mounting type. The supervisors should be set to the following temperature: -40°C~85°C TA. As a result of this supervisor's operation, the output voltage is Open Drain or Open Collector. For this power management, there is an 7mA volt supply current. To find similar IC managements from the manufacturer, you can always search by UC2903. The maximum supply temperature is 15mA.
