BU4331F-TR Product Details

BU4331F-TR Overview


As you can see, this power management is mounted through 4 terminals. Power management is packaged in a Tape & Reel (TR) way. In this IC power you will find 1 functions for you to refer to. On this supervisor, there is a series of 1 channels that can be found. As a reference, this IC power includes SC-82 functions for your convenience. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. IC management conducts in a 2.4V-voltage supply. When a supply voltage of 1 is applied to the power ic, it conducts. Surface Mount is the one that mounts power management. It is possible to subcategorize this power ic as a Power Management Circuits chip. 4 pins are present in total in this power management. This power management system has 4 pins. Supply voltage (Vsup) should be at least 700mV for this power management. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 7V volts. Surface Mount mounting is recommended. You should set the supervisor's temperature during -40°C~125°C TA . While in operation, this supervisor has a voltage output of Push-Pull, Totem Pole. If you want to search for similar IC managements of this manufacturer, you can always refer to BU43*, which is the base power ics number. A maximum supply temperature of 1.75μA can be used with this power management.
