BU4946FVE-TR Overview
As you can see, this power management is mounted through 5 terminals. This power ic is packaged in a way that looks like a Tape & Reel (TR). As a reference, this IC management includes 1 functions for your convenience. It is possible to find on this power management a series of 1 channels. Please find attached SOT-665 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. During operation, the power ic is supplied with a voltage of 2.4V. IC management conducts in a 1-voltage supply. The power management is mounted by Surface Mount. Power Management Circuits is a subcategory of this PMIC chip. The total number of pins on this power management is 5. The pins of the power management system count 5. There should be a minimum voltage supply (Vsup) of 700mV for this PMIC. The supply voltage (Vsup) should not exceed 7V volts in this IC power. The recommended mounting type for IC management is Surface Mount. We recommend setting the supervisors to -40°C~125°C TA degrees. While in operation, this supervisor has a voltage output of Push-Pull, Totem Pole. As far as the supply current of the power management is concerned, it is 550nA. You can always use BU4946, the base supervisor number, to search for similar PMICs of the manufacturer. The power management can work with a maximum supply temperature of 1.75μA.
