BU4837FVE-TR Product Details

BU4837FVE-TR Overview


There are 5 terminals connected to this power management, which makes it easy to mount. A Tape & Reel (TR) package is used to package the power management. Power management is possible to find a series of 1 functions. On this supervisor, there is a series of 1 channels that can be found. In this PMIC, you can find SOT-665 functions for your reference. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. A supply voltage of 2.4V is used to conduct the PMIC chip. IC management is possible to find a succession of 1 voltages that have been checked. The mount is attached to Surface Mount. Power Management Circuits is a subcategory of this PMIC chip. There are a total of 5 pins on power management. 5 pins are present on the power management system. It is recommended that the minimum supply voltage (Vsup) for this IC management should not be less than 700mV volts. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. The recommended mounting type for IC management is Surface Mount. This range of temperature should be set for the supervisors: -40°C~125°C TA. During operation, this power management system outputs Open Drain or Open Collector. The power management's supply current is 550nA. You can always use BU4837, the base supervisor number, to search for similar PMICs of the manufacturer. The power management can work with a maximum supply temperature of 1.58μA.
