BU4319F-TR Product Details

BU4319F-TR Overview


A total of 4 terminals are used to mount this power management. It is packaged with Tape & Reel (TR). As a reference, this IC management includes 1 functions for your convenience. Power management consists of 1 channels, each of which can be used independently. Please find attached SC-82 functions for your reference in this IC power. As with other Simple Reset/Power-On Reset products, this IC management also offers a wide range of benefits. Manage ics operate at 2.4V supply voltages. In a 1 supply voltage, the PMIC chip conducts. The mount is provided by Surface Mount. It is possible to subcategorize this power ic as a Power Management Circuits chip. 4 pins are present in total in this power management. 4 pins are present on the power management system. IC management can only work with a supply voltage of 700mV volts. It is recommended that the maximum supply voltage (Vsup) in this IC power be no more than 7V volts. In this case, Surface Mount is the recommended mounting type. It is recommended that the supervisor be set to this temperature: -40°C~125°C TA. During operation, this power management system outputs Push-Pull, Totem Pole. It is always advisable to use BU43*, the base supervisor number, when searching for similar PMICs from the manufacturer. The maximum supply temperature is 1.75μA.
