BQ29443DRBT Product Details

BQ29443DRBT Overview


The 8-VDFN Exposed Pad package is suitable for battery instrument. A system battery like this uses an analog IC named POWER SUPPLY SUPPORT CIRCUIT. We have 1 channels available. 8 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 4V volts. In this case, this electrical part is mounted in the way of Surface Mount. It is recommended that the power management IC's supply voltage is 25V higher than 25V volts. As far as the Battery Protection functions are concerned, it can be delivered. Temperatures in the -40°C~110°C TA range are ideal for this electronic part. Chemistries for this electrical part are Lithium-Ion. You should leave this transceiver ic set to 17V at all times. There is a use of the BQ29443 family. It is possible to discover the value DETECTION THRESHOLD VOLTAGE IS 4.5V in this smart tools battery when it is used. This power management IC can supply a maximum current of 4mA. Powered by a 2μA supply current, it operates on minimal power.
