BU4928F-TR Overview
As far as the mounting terminals of this voltage supervisor are concerned, it has 4 in total. It is packaged with Tape & Reel (TR). In this PMIC, you can find 1 functions for your reference. On this supervisor, there is a series of 1 channels that can be found. In this IC management you will find SC-82 functions for you to refer to. Compared to other Simple Reset/Power-On Reset products, this PMIC has a lot of benefits to offer. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. By Surface Mount, IC management has been mounted. Power Management Circuits is a subcategory of this PMIC chip. There are a total of 4 pins on power management. The pins of the power management system count 4. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 700mV. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 7V volts. Mounting type Surface Mount is recommended. It is recommended that the supervisor be set to this temperature: -40°C~125°C TA. While this power management is operating, it will output Push-Pull, Totem Pole as the output voltage. Supplied with a operating current of 550nA, this PMIC is capable of fully function as specified. A similar IC managements number of the manufacturer can always be found by using BU4928, the base power ics number. To be able to work, this power management requires 2.5/5V volts of power. At most, voltage supervisor can operate at a supply temperature of 1.4μA.
