UC3903DWTR Overview
As far as the mounting terminals of this voltage supervisor are concerned, it has 18 in total. In terms of packaging, power management follows the Tape & Reel (TR) model. Please refer to this PMIC for 1 functions. There are 4 channels available on this supervisor, and each channel has a different function. In this IC management you will find 18-SOIC (0.295, 7.50mm Width) functions for you to refer to. As with other Multi-Voltage Supervisor products, this IC management also offers a wide range of benefits. During the reflow process, a peak temperature of 260 is specified for the package. When a supply voltage of 15V is applied to the power ic, it conducts. A supply voltage of 4 is used to conduct the PMIC chip. A IC power such as this can be classified as a Power Management Circuits power management system. A total of 18 pins are located on this power management. This power management has 18 pins. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 8V. The maximum supply voltage (Vsup) in this PMIC should not exceed 40V volts. Power management recommends the Surface Mount mounting type. This power management is the recommended temperature range for the supervisors: 0°C~70°C TA. When this power management system is in operation, it produces an output voltage of Open Drain or Open Collector. The supply current of the power management is 7mA. If you want to search for similar IC managements of this manufacturer, you can always refer to UC3903, which is the base power ics number. At the most, voltage supervisor can work with a supply temperature of 18mA.
