BU4822F-TR Overview
It is mounted through 4 terminals on the power management. It is packaged with Tape & Reel (TR). In this PMIC, you can find 1 functions for your reference. This power management is made up of 1 channels which are available in a series format. There are 4-TSOP (0.049, 1.25mm Width) 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. During operation, the power ic is supplied with a voltage of 2.4V. When 1 is applied to the power ic, it conducts. The power management is mounted by a Surface Mount-axis. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. The total number of pins on this power management is 4. 4 pins are on the supervisor. A voltage (Vsup) that doesn't fall below 900mV as the minimum supply voltage (Vsup) should be applied to this IC power in order to ensure its proper operation. Voltage (Vsup) shouldn't exceed 7V volts in this PMIC. Mounting type Surface Mount is recommended. You should set the supervisor's temperature during -40°C~125°C TA . As a result of this supervisor's operation, the output voltage is Open Drain or Open Collector. The supply current of the power management is 550nA. A similar IC managements number of the manufacturer can always be found by using BU48*, the base power ics number. A power supply of 2.5/5V watts is required for the operation of this power management. Voltage supervisor can work with a supply temperature of 1.23μA at the most.
