BU4942F-TR Product Details

BU4942F-TR Overview


A total of 4 terminals are used to mount this power management. Tape & Reel (TR)-packaging is used. For your reference, this IC power includes a list of 1 functions. This power management is made up of 1 channels which are available in a series format. IC management is packaged as a SC-82 package. There are a lot of similarities between this IC management and other Simple Reset/Power-On Reset products. IC management conducts in a 2.4V-voltage supply. Power management conducts at a voltage of 1. Surface Mount is the one that mounts power management. There is a subcategory called Power Management Circuits for this power management. In total, the power management has 4 pins in it. Pin count of the power management is 4. I should note that the minimum supply voltage (Vsup) for this IC management should be at least 900mV, which is the minimum supply voltage that should be applied. This IC power should be powered by no more than 7V volts of supply voltage (Vsup). The recommended mounting type is Surface Mount. It is recommended that the supervisor be set to this temperature: -40°C~125°C TA. When this power management system is in operation, it produces an output voltage of Push-Pull, Totem Pole. The supply current of the power management is 550nA. It is always advisable to use BU4942, the base supervisor number, when searching for similar PMICs from the manufacturer. It requires 2.5/5V watts of power to operate this voltage supervisor. At the most, voltage supervisor can work with a supply temperature of 1.58μA.
