BU4840F-TR Overview
It is mounted through 4 terminals on the power management. Packaged in a Tape & Reel (TR)-shape, IC management comes with a number of features. There are 1 functions included in this PMIC so that you can refer to them. It is possible to find on this power management a series of 1 channels. There are SC-82 functions included in this PMIC so that you can refer to them. Several of the benefits of this PMIC are also shared by other Simple Reset/Power-On Reset products. During operation, the power ic is supplied with a voltage of 2.4V. During operation, the power ic is supplied with a voltage of 1. Using Surface Mount, IC management is mounted. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. In total, IC powers are 4 pins on the board. 4 pins make up the power management. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 700mV. Voltage (Vsup) shouldn't exceed 7V volts in this PMIC. Surface Mount mounting is recommended. It is recommended to set the supervisor's temperature to this range: -40°C~125°C TA. There is an output voltage of Open Drain or Open Collector from this supervisor when it is operating. As far as the supply current of the power management is concerned, it is 550nA. If you want to search for similar IC managements of this manufacturer, you can always refer to BU4840, which is the base power ics number. There is a requirement for 2.5/5V power to power this power management. The maximum supply temperature that PMIC chip can work with is 1.58μA.
