BU4318F-TR Product Details

BU4318F-TR Overview


There are 4 terminals connected to this power management, which makes it easy to mount. This power ic is packaged in a way that looks like a Tape & Reel (TR). There are 1 functions included in this PMIC so that you can refer to them. This power managment ic consists of 1 channels, each of which can be used independently. IC management is packaged as a SC-82 package. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. During operation, the power ic is supplied with a voltage of 2.4V. In a 1 supply voltage, the PMIC chip conducts. By Surface Mount, IC management has been mounted. It is possible to subcategorize this power ic as a Power Management Circuits chip. A total of 4 pins are located on this power management. The pins of the power management system count 4. 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. The recommended mounting type for IC management is Surface Mount. The supervisors should be set to the following temperature: -40°C~125°C TA. The output voltage of this power managment ic during operation is Push-Pull, Totem Pole. It is always advisable to use BU43*, the base supervisor number, when searching for similar PMICs from the manufacturer. A maximum supply temperature of 1.75μA can be used.
