BQ24133RGYR DRV8833PWP DAC081S101CIMKX/N0PB TI原装

The BQ24133 charges the battery in three phases: preconditioning, constant current, and constant voltage. The BQ24133 provides power path selector gate driver ACDRV/CMSRC on input NMOS pair ACFET (Q1) and  RBFET (Q2), and BATDRV on a battery PMOS device (Q3). When the adapter is present, the system is  directly connected to the adapter. Otherwise, the system is connected to the battery. In addition, the power path  prevents battery from boosting back to the input. The BQ24133 charges the battery from a DC source as high as 17 V, including a car battery. The input  overvoltage limit is adjustable through the OVPSET pin. The AVCC, ACP, and ACN pins have a 30-V rating.  When a high-voltage DC source is inserted, Q1 and Q2 remain off to avoid high-voltage damage to the system. For 1-cell applications where the battery is not removable, the system can be directly connected to the battery to  simplify the power path design and reduce the cost. With this configuration, the battery can automatically  supplement the system load if the adapter is overloaded. The BQ24133 is available in a 24-pin, 5.5-mm × 3.5-mm thin VQFN packag。
