BU4339F-TR Product Details

BU4339F-TR Overview


A total of 4 terminals are used to mount this power management. Packaged in the form of a Tape & Reel (TR), power management is easy to use. In this PMIC, you can find 1 functions for your reference. There are 1 channels available on this supervisor, and each channel has a different function. The purpose of this IC power is to provide you with a reference of SC-82 functions. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. IC management conducts at a voltage of 2.4V. During operation, the power ic is supplied with a voltage of 1. The power management is mounted by a Surface Mount-axis. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. It has a total of 4 pins that are attached to IC management. The pins of the power management system count 4. Supply voltage (Vsup) should be at least 700mV for this power management. The supply voltage (Vsup) should not exceed 7V volts in this IC power. The mounting type of the supervisors is Surface MountThe temperature of the supervisors should be set to this range: -40°C~125°C TA. As a result of this supervisor's operation, the output voltage is Push-Pull, Totem Pole. You can always use BU43*, the base supervisor number, to search for similar PMICs of the manufacturer. The maximum supply temperature voltage supervisor can handle is 1.75μA.
