BU4911G-TR Product Details

BU4911G-TR Overview


This voltage supervisor has a total of 5 mounting terminals that can be used for mounting. Tape & Reel (TR)-packaging is used. There are 1 functions included in this PMIC so that you can refer to them. It is possible to find on this power management a series of 1 channels. IC management is packaged as a SC-74A, SOT-753 package. Compared to other Simple Reset/Power-On Reset products, this PMIC has a lot of benefits to offer. When a supply voltage of 2.4V is applied to the power ic, it conducts. IC management conducts in a 1-voltage supply. The mount is provided by Surface Mount. This power ic can be sub-categorized as Power Management Circuits. Taking into account all of the pins, this power management has a total of 5. There are 5 pins on the supervisor. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 700mV. This IC power should be powered by no more than 7V volts of supply voltage (Vsup). The recommended mounting type is Surface Mount. Temperature setting for the supervisors should be -40°C~125°C TA. The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. It is estimated that the voltage supervisor's supply current is 550nA. A similar IC managements number of the manufacturer can always be found by using BU4911, the base power ics number. At most, voltage supervisor can operate at a supply temperature of 880nA.
