Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community bq24715 SLUSBD1B – MARCH 2013 – REVISED SEPTEMBER 2016 bq24715 2-3 Cell NVDC-1 Battery Charger Controller with Ultra-Fast Transient.

General Description

The bq24715 is a NVDC-1 synchronous battery charge controller with low quiescent current, high light load efficiency for 2S or 3S Li-ion battery charging applications, offering low component count.

The power path management allows the system to be regulated at battery voltage but does not drop below the programmable system minimum voltage.

The bq24715 provides N-channel ACFET and RBFET drivers for the power path management.

Key Features

  • 1 6-24V Input SMBus NVDC-1 2-3S Battery Charger Controller.
  • System Instant-on Operation with No Battery or Deeply Discharged Battery.
  • Ultra-Fast Transient Response of 100 µs.
  • Ultra-Low Quiescent Current of 500 µA and High PFM Light Load Efficiency 80% at 20mA load to Meet Energy Star and ErP Lot6.
  • Switching Frequency: 600kHz/800kHz/1MHz.
  • Programmable System/Charge Voltage (16 mV/step), Input/Charge Current (64 mA/step) with High Accuracy.
