BU4941G-TR Overview
There are 5 mounting terminals on the voltage supervisor, each of which has a different function. It is packaged with Tape & Reel (TR). In this IC power you will find 1 functions for you to refer to. Depending on the power managment ic you are looking at, you can find a total of 1 channels. For your reference, this PMIC includes a list of SC-74A, SOT-753 functions. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. Using Surface Mount, IC management is mounted. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. In total, IC powers are 5 pins on the board. There are 5 pins on the power managment ic. I should note that the minimum supply voltage (Vsup) for this IC management should be at least 700mV, which is the minimum supply voltage that should be applied. The maximum supply voltage (Vsup) in this PMIC should not exceed 7V volts. Surface Mount is the recommended mounting type. The temperature of the supervisors should be set to this range: -40°C~125°C TA. The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. The supply current of the power management is 550nA. To find similar IC managements from the manufacturer, you can always search by BU4941. A maximum supply temperature of 1.58μA can be used.
