BU4343FVE-TR Product Details

BU4343FVE-TR Overview


There are 5 mounting terminals on the voltage supervisor, each of which has a different function. Packaged in a Tape & Reel (TR)-shape, IC management comes with a number of features. To assist you, this IC power includes 1 functions. This power managment ic consists of 1 channels, each of which can be used independently. Please refer to power management for SOT-665 functions. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. When a supply voltage of 2.4V is applied to the power ic, it conducts. When a supply voltage of 1 is applied to the power ic, it conducts. By Surface Mount, IC management has been mounted. There is a subcategory of this power ic known as Power Management Circuits. The total number of pins on this power management is 5. This power management has 5 pins. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 700mV. The supply voltage (Vsup) should not exceed 7V volts in this IC power. Surface Mount is the recommended mounting type. It is recommended to set the supervisor's temperature to this range: -40°C~125°C TA. The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. You can always use BU43*, the base supervisor number, to search for similar PMICs of the manufacturer. A maximum supply temperature of 1.75μA can be used.
