BU4931F-TR Overview
A total of 4 terminals are used to mount this power management. This power ic is packaged in a way that looks like a Tape & Reel (TR). Please refer to this PMIC for 1 functions. There are 1 channels on this power managment ic that can be found in a series. There are SC-82 functions included in this PMIC so that you can refer to them. There are a lot of similarities between this IC power and other Simple Reset/Power-On Reset products. There is a voltage supply of 2.4V for the PMIC chip, and the chip conducts at that voltage. There is a voltage supply of 1 for the PMIC chip, and the chip conducts at that voltage. The power management is mounted by Surface Mount. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. There are a total of 4 pins on power management. Power managment ic pin count is 4. It is recommended that the minimum supply voltage (Vsup) for this IC management should not be less than 700mV volts. The maximum supply voltage (Vsup) in this PMIC should not exceed 7V volts. The recommended mounting type is Surface Mount. The temperature of the supervisors should be set to this range: -40°C~125°C TA. During normal operation, this power managment ic can generate Push-Pull, Totem Pole of output voltage. For this power management, there is an 550nA volt supply current. You can always use BU4931, the base supervisor number, to search for similar PMICs of the manufacturer. In order to operate this power management, it requires 2.5/5V volts of power. If you want to work with PMIC chip, you will need to supply PMIC chip with a temperature at least of 1.4μA.
