BU4309F-TR Product Details

BU4309F-TR Overview


Power management is mounted through 4 terminals. Tape & Reel (TR)-packaging is used. Please refer to this PMIC for 1 functions. A series of 1 channels can be found on this supervisor. Please find attached SC-82 functions for your reference in this IC power. With power management, you get a lot of benefits that you won't find in other Simple Reset/Power-On Reset products. In a 2.4V supply voltage, the power management conducts. Power management conducts at a voltage of 1. The mount is attached to Surface Mount. The power management belongs to the Power Management Circuits subcategory. Power management has a total of 4 pins. There are 4 pins on the power managment ic. IC management can only work with a supply voltage of 700mV volts. The supply voltage (Vsup) should not exceed 7V volts in this IC power. Surface Mount is the recommended mounting type. It is recommended to set the supervisor's temperature to this range: -40°C~125°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. To find similar IC managements from the manufacturer, you can always search by BU43*. The maximum supply temperature is 1.75μA.
