BU4921F-TR Overview
It is mounted through 4 terminals on the power management. Tape & Reel (TR)-packaging is used. In this PMIC, you can find 1 functions for your reference. This power managment ic consists of 1 channels, each of which can be used independently. Please refer to power management for SC-82 functions. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. When 2.4V is applied to the power ic, it conducts. In a 1 supply voltage, the PMIC chip conducts. The power management is mounted by a Surface Mount-axis. A IC power such as this can be classified as a Power Management Circuits power management system. Taking into account all of the pins, this power management has a total of 4. Pin count of the power management is 4. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 700mV. The maximum supply voltage (Vsup) is not to exceed 7V volts in this IC management. Surface Mount mounting is recommended. You should set the supervisor's temperature during -40°C~125°C TA . As a result of this supervisor's operation, the output voltage is Push-Pull, Totem Pole. The supply current of the power management is 550nA. A similar IC managements number of the manufacturer can always be found by using BU4921, 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 1.05μA.
