Rohm Semiconductor BU4921G-TR

BU4921G-TR Overview
There are 5 terminals on this power management that allow it to be mounted. A Tape & Reel (TR) package is used to package the power management. In this PMIC, you can find 1 functions for your reference. On this supervisor, there is a series of 1 channels that can be found. In this PMIC, you can find SC-74A, SOT-753 functions for your reference. There are a number of benefits that this PMIC has in common with other Simple Reset/Power-On Reset manage ics. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. Surface Mount mounts IC management. It is possible to subcategorize this power ic as a Power Management Circuits chip. In total, it has 5 pins on IC management. There are 5 pins on the power managment ic. There should be a minimum voltage supply (Vsup) of 700mV for this PMIC. The maximum supply voltage (Vsup) in this PMIC should not exceed 7V volts. Surface Mount is the recommended mounting type. It is recommended that the supervisor be set to this temperature: -40°C~125°C TA. When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. There is a supply current of 550nA for the power management. At the most, voltage supervisor can work with a supply temperature of 1.05μA.
