BU4345F-TR Product Details

BU4345F-TR Overview


There are 4 terminals connected to this power management, which makes it easy to mount. Power management is packaged in a Tape & Reel (TR) way. Please find attached 1 functions for your reference in this IC power. This power management is made up of 1 channels which are available in a series format. Please find attached SC-82 functions for your reference in this IC power. As with other Simple Reset/Power-On Reset products, this IC management also offers a wide range of benefits. When a supply voltage of 2.4V is applied to the power ic, it conducts. Power ics operate at 1 supply voltages. The power management is mounted by Surface Mount. A IC power such as this can be classified as a Power Management Circuits power management system. In total, IC powers are 4 pins on the board. Power managment ic pin count is 4. It is recommended that Vsup should not be less than 900mV for this IC power. This IC power should be powered by no more than 7V volts of supply voltage (Vsup). Power management recommends the Surface Mount mounting type. We recommend setting the supervisors to -40°C~125°C TA degrees. Power management has an output of Push-Pull, Totem Pole during operation. In order to maintain a stable supply current for the power management, 550nA is the recommended value. A similar IC managements number of the manufacturer can always be found by using BU43*, the base power ics number. The maximum supply temperature voltage supervisor can handle is 1.75μA.
