BU4944F-TR Product Details

BU4944F-TR Overview

It is mounted through 4 terminals on the power management. In terms of packaging, power management follows the Tape & Reel (TR) model. Please find attached 1 functions for your reference in this IC power. On this supervisor, there is a series of 1 channels that can be found. There are SC-82 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 a supply voltage of 1 is applied to the power ic, it conducts. The mount is provided by Surface Mount. There is a subcategory of this power ic known as Power Management Circuits. Taking into account all of the pins, this power management has a total of 4. There are 4 pins on the supervisor. It is recommended that Vsup should not be less than 700mV for this IC power. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. Power management recommends the Surface Mount mounting type. This range of temperature should be set for the supervisors: -40°C~125°C TA. During normal operation, this power managment ic can generate Push-Pull, Totem Pole of output voltage. For this power management, there is an 550nA volt supply current. For similar manage ics search of the manufacturer, you can always refer to BU4944, the base PMIC number. The power management must be powered by 2.5/5V volts to function properly. The maximum supply temperature is 1.75μA. When measuring and testing the IC power, it is important to pay attention to the nominal tolerance 1%.
