BU4919F-TR Product Details

BU4919F-TR Overview

Power management is mounted through 4 terminals. Packaged in a Tape & Reel (TR)-shape, IC management comes with a number of features. In this IC power you will find 1 functions for you to refer to. It is possible to find on this power management a series of 1 channels. In this PMIC, you can find SC-82 functions for your reference. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. In a 2.4V supply voltage, the power management conducts. In a 1 supply voltage, the PMIC chip conducts. Using Surface Mount, IC management is mounted. The power management system can be categorized as a Power Management Circuits chip. Taking into account all of the pins, this power management has a total of 4. 4 pins are present on the power management system. There should be a minimum voltage supply (Vsup) of 700mV for this PMIC. There should be no more than 7V volts of maximum supply voltage (Vsup) in this power management. Mounting type Surface Mount is recommended. The temperature of the supervisors should be set to this range: -40°C~125°C TA. During normal operation, this power managment ic can generate Push-Pull, Totem Pole of output voltage. As far as the supply current of the power management is concerned, it is 550nA. It is always advisable to use BU4919, the base supervisor number, when searching for similar PMICs from the manufacturer. The voltage supervisor requires a power source of 2.5/5V volts in order to work correctly. The maximum supply temperature that PMIC chip can work with is 1.05μA.
