BU4843FVE-TR Overview


This power management consists of 5 mounting terminals on which it can be mounted. Power management is packaged in a Tape & Reel (TR) way. To assist you, this IC power includes 1 functions. A series of 1 channels can be found on this supervisor. There are SOT-665 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. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. 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. Taking into account all of the pins, this power management has a total of 5. This power management has 5 pins. IC management can only work with a supply voltage of 700mV volts. The maximum supply voltage (Vsup) in this PMIC should not exceed 7V volts. Surface Mount is the recommended mounting type. The supervisors should be set to the following temperature: -40°C~125°C TA. During normal operation, this power managment ic can generate Open Drain or Open Collector of output voltage. Supplied with a operating current of 550nA, this PMIC is capable of fully function as specified. For similar manage ics search of the manufacturer, you can always refer to BU4843, the base PMIC number. The maximum supply temperature voltage supervisor can handle is 1.75μA.
