BU4945FVE-TR Overview


As you can see, this power management is mounted through 5 terminals. There is a Tape & Reel (TR)-packaging method applied to IC management. The purpose of this IC management is to provide you with a reference of 1 functions. There are 1 channels available on this supervisor, and each channel has a different function. IC management is packaged as a SOT-665 package. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. When a supply voltage of 2.4V is applied to the power ic, it conducts. During operation, the power ic is supplied with a voltage of 1. The mount is provided by Surface Mount. There is a subcategory called Power Management Circuits for this power management. In total, the power management has 5 pins in it. 5 pins are present on the power management system. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 700mV. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. Surface Mount mounting is recommended. The supervisors should be set to the following temperature: -40°C~125°C TA. While in operation, this supervisor has a voltage output of Push-Pull, Totem Pole. For this power management, there is an 550nA volt supply current. If you want to search for similar IC managements of this manufacturer, you can always refer to BU4945, which is the base power ics number. Voltage supervisor can work with a supply temperature of 1.75μA at the most.
