BU4839G-TR Product Details

BU4839G-TR Overview


As far as the mounting terminals of this voltage supervisor are concerned, it has 5 in total. Tape & Reel (TR)-packaging is used. Power management is possible to find a series of 1 functions. On this supervisor, there is a series of 1 channels that can be found. Please find attached SC-74A, SOT-753 functions for your reference in this IC power. This IC power shares lots of benefits with other Simple Reset/Power-On Reset products. There is a voltage supply of 2.4V for the PMIC chip, and the chip conducts at that voltage. Power ics operate at 1 supply voltages. The mount is provided by Surface Mount. The power management belongs to the Power Management Circuits subcategory. In total, the power management has 5 pins in it. There are 5 pins on the power managment ic. Supply voltage (Vsup) should be at least 700mV for this power management. 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 . As this power managment ic operates, it is able to produce an output voltage of Open Drain or Open Collector. It is estimated that the voltage supervisor's supply current is 550nA. If you want to search for similar IC managements of this manufacturer, you can always refer to BU4839, which is the base power ics number. At the most, voltage supervisor can work with a supply temperature of 1.58μA.
