BU4840F-TR Product Details

BU4840F-TR Overview


Power management is mounted through 4 terminals. There is a Tape & Reel (TR)-packaging method applied to IC management. As a reference, this IC management includes 1 functions for your convenience. A series of 1 channels can be found on this supervisor. The purpose of this IC power is to provide you with a reference of SC-82 functions. As with other Simple Reset/Power-On Reset products, this IC management also offers a wide range of benefits. IC management conducts at a voltage of 2.4V. When 1 is applied to the power ic, it conducts. The mount is attached to Surface Mount. There is a subcategory of this power ic known as Power Management Circuits. The total number of pins on this power management is 4. This power management system has 4 pins. There should be a minimum voltage supply (Vsup) of 700mV for this PMIC. During this IC power, the maximum supply voltage (Vsup) should not exceed 7V volts. The recommended mounting type is Surface Mount. You should set the supervisor's temperature during -40°C~125°C TA . As a result of this supervisor's operation, the output voltage is Open Drain or Open Collector. For this power management, there is an 550nA volt supply current. If you want to search for similar IC managements of this manufacturer, you can always refer to BU4840, which is the base power ics number. This power management requires 2.5/5V power to work. A maximum supply temperature of 1.58μA can be used with this power management.
