BU4811FVE-TR Product Details

BU4811FVE-TR Overview


A total of 5 terminals are used to mount this power management. Tape & Reel (TR)-packaging is used. Please refer to this PMIC for 1 functions. There are 1 channels on this power managment ic that can be found in a series. In this PMIC, you can find SOT-665 functions for your reference. As with other Simple Reset/Power-On Reset products, this IC management also offers a wide range of benefits. When 2.4V is applied to the power ic, it conducts. During operation, the power ic is supplied with a voltage of 1. Using Surface Mount, IC management is mounted. The power management system can be categorized as a Power Management Circuits chip. 5 pins are present in total in this power management. This power management system has 5 pins. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than 700mV. The maximum supply voltage (Vsup) is not to exceed 7V volts in this IC management. Surface Mount is the recommended mounting type. The supervisors should be set to the following temperature: -40°C~125°C TA. As this power managment ic operates, it is able to produce an output voltage of Open Drain or Open Collector. In order to maintain a stable supply current for the power management, 550nA is the recommended value. It is always advisable to use BU4811, the base supervisor number, when searching for similar PMICs from the manufacturer. Voltage supervisor can work with a supply temperature of 880nA at the most.
