BU4814F-TR Overview


This power management consists of 4 mounting terminals on which it can be mounted. This power ic is packaged in a way that looks like a Tape & Reel (TR). Please find attached 1 functions for your reference in this IC power. Power management consists of 1 channels, each of which can be used independently. The purpose of this IC power is to provide you with a reference of SC-82 functions. Several of the benefits of this PMIC are also shared by other Simple Reset/Power-On Reset products. Manage ics operate at 2.4V supply voltages. There is a voltage supply of 1 for the PMIC chip, and the chip conducts at that voltage. Surface Mount is the one that mounts power management. It is possible to subcategorize this power ic as a Power Management Circuits chip. It has a total of 4 pins that are attached to IC management. 4 pins are on the supervisor. There should be a minimum voltage supply (Vsup) of 700mV for this PMIC. There should be no more than 7V volts of 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. The output voltage of this power managment ic during operation is Open Drain or Open Collector. For this power management, there is an 550nA volt supply current. To find similar IC managements from the manufacturer, you can always search by BU4814. It is necessary to have 2.5/5V volts of power in order for this voltage supervisor to operate. The power management can work with a maximum supply temperature of 1.05μA.
