BQ29312PWRG4 Product Details

BQ29312PWRG4 Overview


24-TSSOP (0.173, 4.40mm Width) is the appropriate package for battery instrument. Analog IC POWER SUPPLY MANAGEMENT CIRCUIT is used in this power IC. The number of channels available is 1. In total, it has 24 pins. The case is labeled Tape & Reel (TR). For mounting, use Surface Mount. In Surface Mount, this electronic component is mounted. It is capable of delivering the Battery Protection functions. This electric part performs best at temperatures in the range of -25°C~85°C TA. There is Lithium Ion/Polymer in the battery chemistry of this electronic component. It is important to keep this battery management IC set to 14V at all times. The family BQ29312 is the basis for it. There must be a voltage higher than 4.5V (Vsup) on the supply. Supply current (Isup) must not exceed 0.1mA. A voltage in the range of 25V is specified for this power management IC's operating supply voltage. It is possible to supply the battery management IC with a maximum current of 200μA.
