BU4939G-TR Overview
As you can see, this power management is mounted through 5 terminals. It is packaged with Tape & Reel (TR). Please refer to this PMIC for 1 functions. It is possible to find on this power management a series of 1 channels. There are SC-74A, SOT-753 functions included in this PMIC so that you can refer to them. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. Manage ics operate at 2.4V supply voltages. IC management is possible to find a succession of 1 voltages that have been checked. Using Surface Mount, IC management is mounted. This power ic can be sub-categorized as Power Management Circuits. 5 pins are present in total in this power management. Pin count of the power management is 5. Supply voltage (Vsup) should be at least 700mV for this power management. There should be no more than 7V volts of maximum supply voltage (Vsup) in this power management. The mounting type of the supervisors is Surface MountThe supervisors should be set to the following temperature: -40°C~125°C TA. While this power management is operating, it will output Push-Pull, Totem Pole as the output voltage. The power management's supply current is 550nA. You can always use BU4939, the base supervisor number, to search for similar PMICs of the manufacturer. The maximum supply temperature that PMIC chip can work with is 1.58μA.
