BU4940G-TR Product Details

BU4940G-TR Overview


A total of 5 terminals are used to mount this power management. Packaged in the form of a Tape & Reel (TR), power management is easy to use. There are 1 functions included in this PMIC so that you can refer to them. Power management consists of 1 channels, each of which can be used independently. Please find attached SC-74A, SOT-753 functions for your reference in this IC power. There are many benefits that this IC power shares with other Simple Reset/Power-On Reset products as well. When a supply voltage of 2.4V is applied to the power ic, it conducts. Power management conducts at a voltage of 1. Surface Mount mounts IC management. In this case, this PMIC chip can be sub-categorized as a Power Management Circuits chip. The total number of pins on this power management is 5. 5 pins make up the power management. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 700mV. The maximum supply voltage (Vsup) is not to exceed 7V volts in this IC management. The mounting type of the supervisors is Surface MountWe recommend setting the supervisors to -40°C~125°C TA degrees. While this power management is operating, it will output Push-Pull, Totem Pole as the output voltage. The supervisor's supply current is specified to 550nA. If you want to search for similar IC managements of this manufacturer, you can always refer to BU49*, which is the base power ics number. A maximum supply temperature of 1.58μA can be used with this power management.
