Resumen del producto

The BQ24032ARHLR is a single-chip charge and system power-path management Integrated Circuit features highly integrated Li-ion linear chargers and system power-path management device targeted at space-limited portable applications. The IC offers integrated USB-port and DC supply, power-path management with autonomous power-source selection, power FETs and current sensors, high accuracy current and voltage regulation, charge status and charge termination, in a single monolithic device. The bqTINY™ IC powers the system while independently charging the battery. This feature reduces the charge and discharge cycles on battery, allows for proper charge termination and allows the system to run with an absent or defective battery pack. These feature also allows for the system to instantaneously turn on from an external power source in the case of a deeply discharged battery pack. The IC is focused on supplying continuous power to system when available from the AC, USB or battery sources.
  • Integrated Dynamic Power Path Management (DPPM)
  • Allows the AC adapter or the USB port to simultaneously power the system and charge the battery
  • Power supplement mode allows battery to supplement the USB or AC input current
  • Autonomous power source selection (AC adapter or USB)
  • Integrated USB charge control with selectable
  • Dynamic total current management for USB
  • Thermal regulation for charge control
  • Charge status outputs for LED or system interface
  • Indicates charge and fault conditions
  • Reverse current, short-circuit and thermal protection
  • Power good (AC adapter and USB port present) status outputs
  • Green product and no Sb/Br

Aplicaciones

Administración de Potencia, Electrónica de Consumo, Dispositivos Portátiles

Advertencias

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
