BU4309G-TR Product Details

BU4309G-TR Overview


There are 5 terminals on this power management that allow it to be mounted. In terms of packaging, power management follows the Tape & Reel (TR) model. For your reference, this IC power includes a list of 1 functions. This power managment ic consists of 1 channels, each of which can be used independently. There are SC-74A, SOT-753 functions included in this PMIC so that you can refer to them. Several of the benefits of this PMIC are also shared by other Simple Reset/Power-On Reset products. During operation, the power ic is supplied with a voltage of 2.4V. When a supply voltage of 1 is applied to the power ic, it conducts. Surface Mount is the one that mounts power management. Power Management Circuits is a subcategory of this PMIC chip. The total number of pins on this power management is 5. There are 5 pins on the supervisor. 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. This IC power should be powered by no more than 7V volts of supply voltage (Vsup). Power management recommends the Surface Mount mounting type. The temperature of the supervisors should be set to this range: -40°C~125°C TA. While this power management is operating, it will output Push-Pull, Totem Pole as the output voltage. To find similar IC managements from the manufacturer, you can always search by BU43*. A maximum supply temperature of 1.75μA can be used.
