BU4945F-TR Overview

There are 4 mounting terminals on the voltage supervisor, each of which has a different function. Packaged in a Tape & Reel (TR)-shape, IC management comes with a number of features. To assist you, this IC power includes 1 functions. Depending on the power managment ic you are looking at, you can find a total of 1 channels. IC management is packaged as a SC-82 package. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. IC management conducts in a 2.4V-voltage supply. There is a voltage supply of 1 for the PMIC chip, and the chip conducts at that voltage. The power management is mounted by a Surface Mount-axis. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. In total, it has 4 pins on IC management. 4 pins are on the supervisor. It is recommended that Vsup should not be less than 700mV for this IC power. There should be no more than 7V volts of maximum supply voltage (Vsup) in this power management. The mounting type of the supervisors is Surface MountIt is recommended to set the supervisor's temperature to this range: -40°C~125°C TA. When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. The supply current of the power management is 550nA. You can always use BU4945, the base supervisor number, to search for similar PMICs of the manufacturer. It requires 2.5/5V watts of power to operate this voltage supervisor. The maximum supply temperature voltage supervisor can handle is 1.75μA.
