BU4220F-TR Overview

This power management consists of 4 mounting terminals on which it can be mounted. Packaged in the form of a Tape & Reel (TR), power management is easy to use. Please refer to this PMIC for 1 functions. This power managment ic consists of 1 channels, each of which can be used independently. As a reference, this IC power includes SC-82 functions for your convenience. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. 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. The power management system can be categorized as a Power Management Circuits chip. The total number of pins on this power management is 4. Pin count of the power management is 82. IC management can only work with a supply voltage of 700mV volts. There should be no more than 7V volts of maximum supply voltage (Vsup) in this power management. Power management recommends the Surface Mount mounting type. This power management is the recommended temperature range for the supervisors: -40°C~125°C TA. Power management has an output of Open Drain or Open Collector during operation. You can always use BU42*, the base supervisor number, to search for similar PMICs of the manufacturer. The maximum supply temperature is 1.75μA.
