UC2903Q Overview
As you can see, this power management is mounted through 20 terminals. Packaged in a Tube-shape, IC management comes with a number of features. 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. For your reference, this PMIC includes a list of 20-LCC (J-Lead) functions. It is a IC power that shares many benefits with other products from the Multi-Voltage Supervisor line. In order to ensure a good reflow performance, the package peak reflow temperature must be set at 260. During operation, the power ic is supplied with a voltage of 15V. IC management is possible to find a succession of 4 voltages that have been checked. By Surface Mount, IC management has been mounted. There is a subcategory of this power ic known as Power Management Circuits. In total, the power management has 20 pins in it. 20 pins make up the power management. 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. Voltage (Vsup) shouldn't exceed 40V volts in this PMIC. The recommended mounting type for IC management is Surface Mount. The temperature of the supervisors should be set to this range: -40°C~85°C TA. As this power managment ic operates, it is able to produce an output voltage of Open Drain or Open Collector. Supplied with a operating current of 7mA, this PMIC is capable of fully function as specified. If you want to search for similar IC managements of this manufacturer, you can always refer to UC2903, which is the base power ics number. The power management can work with a maximum supply temperature of 15mA.
