BU4813F-TR Overview

This power management consists of 4 mounting terminals on which it can be mounted. In terms of packaging, power management follows the Tape & Reel (TR) model. As a reference, this IC management includes 1 functions for your convenience. This power managment ic consists of 1 channels, each of which can be used independently. There are SC-82 functions included in this PMIC so that you can refer to them. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. When a supply voltage of 2.4V is applied to the power ic, it conducts. IC management is possible to find a succession of 1 voltages that have been checked. Surface Mount is the one that mounts power management. There is a subcategory of this power ic known as Power Management Circuits. In total, it has 4 pins on IC management. The pins of the power management system count 4. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 700mV. There should be no more than 7V volts of supply voltage (Vsup) in this power management. A Surface Mount mounting type is recommended. 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 Open Drain or Open Collector. There is a 550nA supply current present in the power management. You can always use BU4813, the base supervisor number, to search for similar PMICs of the manufacturer. A power supply of 2.5/5V watts is required for the operation of this power management. Voltage supervisor can work with a supply temperature of 880nA at the most.
