Rohm Semiconductor BU4920FVE-TR

BU4920FVE-TR Overview
A total of 5 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 a total of 1 channels on this supervisor, and they are arranged in a series. Please refer to power management for SOT-665 functions. Compared to other Simple Reset/Power-On Reset products, this PMIC has a lot of benefits to offer. Manage ics operate at 2.4V supply voltages. Power ics operate at 1 supply voltages. The power management is mounted by Surface Mount. There is a subcategory of this power ic known as Power Management Circuits. There are a total of 5 pins on power management. Power managment ic pin count is 5. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 700mV. There should be no more than 7V volts of supply voltage (Vsup) in this power management. Mounting type Surface Mount is recommended. You should set the supervisor's temperature during -40°C~125°C TA . The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. It is estimated that the voltage supervisor's supply current is 550nA. It is always advisable to use BU4920, the base supervisor number, when searching for similar PMICs from the manufacturer. A maximum supply temperature of 1.05μA can be used with this power management.
