General Description

The bq24707 and bq24707A devices are highefficiency, synchronous battery chargers, offering low component count for space-constrained, multichemistry battery charging applications.

SMBus controlled input current, charge current, and charge voltage DACs allow for very high regulation accuracies that can be easily programmed by the system power management micro-controller.

The IC uses the internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current.

Key Features

  • 1 SMBus Host-Controlled NMOS-NMOS Synchronous Buck Converter With Programmable 615 kHz, 750 kHz, and 885 kHz Switching Frequency.
  • Real-Time System Control on ILIM Pin to Limit Charge Current.
  • Enhanced Safety Features for Overvoltage Protection, Overcurrent Protection, Battery, Inductor, and MOSFET Short-Circuit Protection.
  • Programmable Input Current, Charge Voltage, Charge Current Limits.
  • ±0.5% Charge Voltage Accuracy up to 19.2 V.
  • ±3% Charge.
