BU4947F-TR Overview

This power management consists of 4 mounting terminals on which it can be mounted. Tape & Reel (TR)-packaging is used. Power management is possible to find a series of 1 functions. Depending on the power managment ic you are looking at, you can find a total of 1 channels. There are SC-82 functions included in this PMIC so that you can refer to them. As with other Simple Reset/Power-On Reset products, this IC management also offers a wide range of benefits. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. Surface Mount mounts IC management. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. Power management has a total of 4 pins. 4 pins are present on the power management system. 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. The recommended mounting type for IC management is Surface Mount. 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. There is a supply current of 550nA for the power management. It is always advisable to use BU4947, the base supervisor number, when searching for similar PMICs from the manufacturer. In order to operate this power management, it requires 2.5/5V volts of power. A maximum supply temperature of 1.75μA can be used with this power management.
