UC3903N Overview


It is mounted through 18 terminals on the power management. Packaged in a Tube-shape, IC management comes with a number of features. Please refer to this PMIC for 1 functions. It is possible to find on this power management a series of 4 channels. Please refer to power management for 18-DIP (0.300, 7.62mm) functions. As with other Multi-Voltage Supervisor products, this IC management also offers a wide range of benefits. Manage ics operate at 15V supply voltages. IC management is possible to find a succession of 4 voltages that have been checked. The power management belongs to the Power Management Circuits subcategory. 18 pins are present in total in this power management. There are 18 pins on the supervisor. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 8V. This IC power should be powered by no more than 40V volts of supply voltage (Vsup). Mounting type Through Hole is recommended. The temperature of the supervisors should be set to this range: 0°C~70°C TA. During operation, this power management system outputs Open Drain or Open Collector. The supervisor's supply current is specified to 7mA. For similar manage ics search of the manufacturer, you can always refer to UC3903, the base PMIC number. The power management can work with a maximum supply temperature of 18mA. For this IC management, 1 outputs are available.
