BU4927F-TR Product Details

BU4927F-TR Overview


It is mounted through 4 terminals on the power management. Tape & Reel (TR)-packaging is used. To assist you, this IC power includes 1 functions. It is possible to find on this power management a series of 1 channels. For your reference, this PMIC includes a list of SC-82 functions. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. Manage ics operate at 2.4V supply voltages. When a supply voltage of 1 is applied to the power ic, it conducts. Surface Mount is the one that mounts power management. The power management belongs to the Power Management Circuits subcategory. It has a total of 4 pins that are attached to IC management. 4 pins are present on the power management system. It is recommended that the minimum supply voltage (Vsup) for this IC management should not be less than 700mV volts. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. The mounting type of the supervisors is Surface MountTemperature setting for the supervisors should be -40°C~125°C TA. There is an output voltage of Push-Pull, Totem Pole from this supervisor when it is operating. The supply current of the power management is 550nA. For similar manage ics search of the manufacturer, you can always refer to BU4927, the base PMIC number. There is a requirement for 2.5/5V power to power this power management. The maximum supply temperature is 1.23μA.
