BU4231F-TR Product Details

BU4231F-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 a total of 1 channels on this supervisor, and they are arranged in a series. For your reference, this PMIC includes a list of SC-82 functions. 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. There is a voltage supply of 1 for the PMIC chip, and the chip conducts at that voltage. Surface Mount is the one that mounts power management. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. In total, IC powers are 4 pins on the board. Pin count of the power management is 82. It is recommended that Vsup should not be less than 700mV for this IC power. In this PMIC, the maximum supply voltage (Vsup) should not exceed 7V volts. Mounting type Surface Mount is recommended. You should set the supervisor's temperature during -40°C~125°C TA . When this power management system is in operation, it produces an output voltage of Open Drain or Open Collector. For similar manage ics search of the manufacturer, you can always refer to BU42*, the base PMIC number. The maximum supply temperature voltage supervisor can handle is 1.75μA.
