BU4842F-TR Overview


Power management is mounted through 4 terminals. In terms of packaging, power management follows the Tape & Reel (TR) model. In this PMIC, you can find 1 functions for your reference. Power management consists of 1 channels, each of which can be used independently. To assist you, this PMIC includes SC-82 functions. Compared to other Simple Reset/Power-On Reset products, this PMIC has a lot of benefits to offer. When a supply voltage of 2.4V is applied to the power ic, it conducts. There is a voltage supply of 1 for the PMIC chip, and the chip conducts at that voltage. Using Surface Mount, IC management is mounted. As a subcategory, this PMIC chip can be categorized as Power Management Circuits. A total of 4 pins are located on this power management. 4 pins are on the supervisor. In order for this PMIC to work correctly, the minimum supply voltage (Vsup) should be greater than -300mV. In this PMIC, the maximum supply voltage (Vsup) should not exceed 7V volts. The recommended mounting type is Surface Mount. Temperature setting for the supervisors should be -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. To find similar IC managements from the manufacturer, you can always search by BU48*. There is a requirement for 2.5/5V power to power this power management. A maximum supply temperature of 1.58μA can be used with this power management.
