UC3909DWTRG4 Product Details

UC3909DWTRG4 Overview


The SOIC package is suitable for battery instrument. A system battery like this uses an analog IC named BATTERY CHARGE CONTROLLER. 20 pins are attached to it. Tape & Reel (TR) is the case number of the package. The voltage supply for this electric component should not be less than 7.5V volts. The family name of this electrical component is Power Management Circuits. It is recommended that the power management IC's supply voltage is 40V higher than 40V volts. In order for this system battery to be activated, its value cannot be less than 0. A temperature below 70°C is recommended for its use. The battery protector ic is powered by a volt of 15V. You should leave this transceiver ic set to 15V at all times. The power IC has a total of 20 pins. (Isup) must have a maximum current of 19mA.
