BU4321G-TR Product Details

BU4321G-TR Overview


It is mounted through 5 terminals on the power management. It is packaged with Tape & Reel (TR). In this PMIC, you can find 1 functions for your reference. There are a total of 1 channels on this supervisor, and they are arranged in a series. To assist you, this PMIC includes SC-74A, SOT-753 functions. This IC power shares lots of benefits with other Simple Reset/Power-On Reset products. When a supply voltage of 2.4V is applied to the power ic, it conducts. IC management conducts in a 1-voltage supply. Surface Mount is the one that mounts power management. This power ic can be sub-categorized as Power Management Circuits. 5 pins are present in total in this power management. This power management system has 5 pins. A voltage (Vsup) that doesn't fall below 700mV as the minimum supply voltage (Vsup) should be applied to this IC power in order to ensure its proper operation. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 7V volts. Surface Mount mounting is recommended. You should set the supervisor's temperature during -40°C~125°C TA . When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. A similar IC managements number of the manufacturer can always be found by using BU43*, the base power ics number. At the most, voltage supervisor can work with a supply temperature of 1.75μA.
