BQ24260/61 Li-Ion Battery Charger with USB OTG

Product Description

The Texas Instruments bq24260 and bq24261 are single cell Li-Ion battery charger and system power path management devices that can be run from either a USB port or wall adapter supply.

The power path feature allows the devices to power the system from a high efficiency DC-DC converter while simultaneously and independently charging the battery.
The power path also allows the battery to supplement the system current requirements when the adapter cannot.

Many features are programmable using the I2C interface. To support USB OTG applications, the bq2426x is configurable to boost the battery voltage to 5V and supply up to 1A at the input.
The battery is charged with three phases: precharge, constant current and constant voltage. Thermal regulation prevents the die temperature from exceeding 125°C.

Additionally, a JEITA compatible battery pack thermistor monitoring input (TS) is included to prevent the battery from charging outside of its safe temperature range.

Other features include:

  • Integrated 17mΩ Power Path MOSFET and optional BGATE control to maximise battery life and enable instant startup From a deeply discharged battery or no battery at all.
  • 30V Input Rating with Over-Voltage Protection Supports 5V USB2.0/3.0 and 12V USB
  • Power Delivery (bq24261)
  • Small Solution Size In a 2.4mm x 2.4mm 36-ball WCSP or 4mm × 4mm QFN-24 Package
  • Thermal Regulation Protection for Input Current Control
  • Thermal Shutdown and Protection.

Typical applications

Smartphone and Tablets, Handheld Products, Power Banks and External Battery Packs, Small Power Tools, Portable Media Players and Gaming.
