BU4318G-TR Product Details

BU4318G-TR Overview


A total of 5 terminals are used to mount this power management. A Tape & Reel (TR) package is used to package the power management. Please find attached 1 functions for your reference in this IC power. There are 1 channels on this power managment ic that can be found in a series. Please find attached SC-74A, SOT-753 functions for your reference in this IC power. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. When 2.4V is applied to the power ic, it conducts. When 1 is applied to the power ic, it conducts. Surface Mount is the one that mounts power management. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. There are a total of 5 pins on power management. Power managment ic pin count is 5. 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). Power management' mounting is recommended to be done with the Surface Mount type of mounting. It is recommended to set the supervisor's temperature to this range: -40°C~125°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. A similar IC managements number of the manufacturer can always be found by using BU43*, the base power ics number. If you want to work with PMIC chip, you will need to supply PMIC chip with a temperature at least of 1.75μA.

BU4318G-TR Features


Simple Reset/Power-On Reset type
