Product Overview
The BQ24133RGYT is a synchronous switch-mode Li-ion and Li-polymer stand-alone Battery Charger offers a constant-frequency synchronous PWM controller with high accuracy regulation of input current, charge current and voltage. The BQ24133 closely monitors the battery pack temperature to allow charge only in a preset temperature window. The bq24133 charges one, two, or three cells (selected by CELL pin) at a fixed 4.2 V/cell. It charges the battery in three phases: preconditioning, constant current and constant voltage. It 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 qualified 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. It charges the battery from a DC source as high as 17V, including a car battery.
- Up to 92% efficiency
- Automatic power path selector between adapter and battery
- Dynamic power management
- Integrated 20V switching MOSFETs
- Integrated bootstrap diode
- Internal digital soft start
- Thermal shutdown
- Cycle-by-cycle current limit
- Adjustable input overvoltage protection
- Green product and no Sb/Br
Applications
Power Management, Computers & Computer Peripherals, Medical, Portable Devices, Consumer Electronics, Industrial
