BQ29311PW Product Details

BQ29311PW Overview


The 24-TSSOP (0.173, 4.40mm Width) package is suitable for battery instrument. A system battery like this uses an analog IC named POWER SUPPLY SUPPORT CIRCUIT. We have 5 channels available. 24 pins are attached to it. Tube is the case number of the package. 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 -25°C~85°C TA range are ideal for this electronic part. Chemistries for this electrical part are Lithium Ion/Polymer. You should leave this transceiver ic set to 14V at all times. There is a use of the BQ29311 family. This power management IC can supply a maximum current of 25mA.
