BU4344F-TR Product Details

BU4344F-TR Overview


There are 4 terminals connected to this power management, which makes it easy to mount. Packaged in a Tape & Reel (TR)-shape, IC management comes with a number of features. Power management is possible to find a series of 1 functions. There are 1 channels available on this supervisor, and each channel has a different function. As a reference, this IC power includes SC-82 functions for your convenience. 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. When 1 is applied to the power ic, it conducts. The mount is provided by Surface Mount. The power management belongs to the Power Management Circuits subcategory. A total of 4 pins are located on this power management. Power managment ic pin count is 4. IC management can only work with a supply voltage of 900mV volts. The maximum supply voltage (Vsup) in this PMIC should not exceed 7V volts. The recommended mounting type for IC management is Surface Mount. It is recommended that the supervisor be set to this temperature: -40°C~125°C TA. Power management has an output of Push-Pull, Totem Pole during operation. The power management's supply current is 550nA. For similar manage ics search of the manufacturer, you can always refer to BU43*, the base PMIC number. A maximum supply temperature of 1.75μA can be used.
