BU4821F-TR Overview
There are 4 terminals connected to this power management, which makes it easy to mount. Packaged in the form of a Tape & Reel (TR), power management is easy to use. The purpose of this IC management is to provide you with a reference of 1 functions. There are 1 channels available on this supervisor, and each channel has a different function. In this PMIC, you can find 4-TSOP (0.049, 1.25mm Width) functions for your reference. Compared to other Simple Reset/Power-On Reset products, this PMIC has a lot of benefits to offer. IC management conducts at a voltage of 2.4V. Power ics operate at 1 supply voltages. Power management is included in the Surface Mount mount. The power management system can be categorized as a Power Management Circuits chip. There are a total of 4 pins on power management. 4 pins are present on the power management system. A voltage (Vsup) that doesn't fall below 700mV as the minimum supply voltage (Vsup) should be applied to this IC power in order to ensure its proper operation. The maximum supply voltage (Vsup) is not to exceed 7V volts in this IC management. Mounting type Surface Mount is recommended. The temperature of the supervisors should be set to this range: -40°C~125°C TA. While in operation, this supervisor has a voltage output of Open Drain or Open Collector. In order to maintain a stable supply current for the power management, 550nA is the recommended value. For similar manage ics search of the manufacturer, you can always refer to BU48*, the base PMIC number. It requires 2.5/5V watts of power to operate this voltage supervisor. Voltage supervisor can work with a supply temperature of 1.05μA at the most.
