BU4940FVE-TR Overview


There are 5 mounting terminals on the voltage supervisor, each of which has a different function. This power ic is packaged in a way that looks like a Tape & Reel (TR). In this IC power you will find 1 functions for you to refer to. On this supervisor, there is a series of 1 channels that can be found. Please refer to power management for SOT-665 functions. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. When 2.4V is applied to the power ic, it conducts. IC management conducts in a 1-voltage supply. By Surface Mount, IC management has been mounted. The power management belongs to the Power Management Circuits subcategory. In total, IC powers are 5 pins on the board. 5 pins are on the supervisor. It is recommended that Vsup should not be less than 700mV for this IC power. Voltage (Vsup) shouldn't exceed 7V volts in this PMIC. Surface Mount is the recommended mounting type. You should set the supervisor's temperature during -40°C~125°C TA . As a result of this supervisor's operation, the output voltage is Push-Pull, Totem Pole. Supplied with a operating current of 550nA, 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 BU4940, which is the base power ics number. The maximum supply temperature is 1.58μA.
